NIUGINI CAVER .. J NUMBER 3 54 The 5ollt.hern Highlands contain and thicker limestone than any dtstxict in the country, and yet it has been one of the nele.c.ted, cave-wise 9 until recently o Only in the last few years as this primitive area has been opened up to the outside world have cavers been active there. In the early sixties the Port Moresby Speleological Society did not visit the area because it was considared that the red tape to.get into the restricted areas YJas formidable than the mountains themselves. And formidable_. indeed is some of the limestone country. Even the geomorphologist So WO Carey was moved to superlatives in describing the limestone country to the South .. j.n the Strickland-Purari foothill areao Carey (1938) wrote9 -. "Overland transport through this reg:i.on is of ten a task of extreme difficulty. The has a deplorable tendency to form sheer walls along fa.ult-lines9 and precipitous chasms and gorges along the st.reams.. On the limestone plateau the surf ace is broken by countless caldera and sinkholes 200-300 feet aeep with sides of jac;ged rock9 and the day's journey may bea continuous series of descents and ascents through these depressionso Tbe surface a litter of great limestone blocks with knife-edl;::.ed projections which lacerate and gash the boots and legs of and the feet of his carriers ..... .. mo.a-t f "C-Ountry." ' Little has been written on t.Q.e caves in the area., Neil Ryan's article on the El,rave area (Ryan t970) was the first to give specifio detai1s on caves and locations7 although the geomorphologists Jennings and and Williams have studiQ. karst. in the area earlier o WilJ.iams {in press) goes into more.detail on the caving potential, but gives few details. Various authors of the "kiap turned writer'' variet3 have mentioned caves in the general areao In this issue we bring four articles from the Southern Highlands including notes on the caves from near Mendi. It is hoped to publish urtber articles later. With the biggest caving expedition to come to Papua Guine? now in the field 1n the Southern Highlands, there should be&much more known about caves shortlyo The Mendi group is not now active following an a-ctive t1e:t'iod over the past few years 9 but hopeful i_y caving will pick Up again soon.

NIUGINI CAVER VOLUME 1 NUMBER 3 NOTE ON CAVES AND. A LEGEND, . SOUTHERN HIGHLANDS e b I a Lex Br•wn * The following notes on several caves and a'legend in the Mendi area, SoHoDG9 were provided by John Grant from Brisbane who spent a University vacation working C.D,.VVo in the Mendi area 1967/680 are eave entrances, quite large t• the South west of Mendi near the quarry and at the foot of the •liffs. (See Article by Van Amstel, this issue) The caves may have used by the villagers as a burial ground. An uitderground river, a tributary of the Erave, enters a eave 4eo m upstream of a road crossing on the read 8-15 km East of Mendi. The river is 6 m wide and 0.5 m deep, and enters a hole about 2.5 m in diametero It may be accessible in the dry seasono The river is believed to re• emerge 1-1.5 km downstream through sand and gravel banks. (Photographs of this entrance are now held in the University of Queensland Speleological Society's slide libraryo) There is a legend of a cave that goes from a range from one valley to the next North east of Mendi towards Hagen. The cave would be 24 km longo It is not now accessible (20-40 years later) oecause of rock falls and also fears of the villagers. * 45 Station Road9 Indooroopilly1 Queenslando 40680 * * * Il\fVK:iTIGATIONS ON THE RIVER, SOUTHERN HIGHLANDS DISTRICT Ro Michael Bourke * Being a tale of some streams that fltw the "wrong" way and sometimes the "right" way; springs:; wild limeston, landscapes; and a natural bridgeo A unit of water flow equal to a cubic metre per second, i.eo, a flow a metre wide and deep flowing at one metre per second. * D.AoS.Fo, Keravat, East New Britain.

General term for solution controlled lapdforms1 particularly where connected vvi th underground d"twersion of dratnage. In May-June 1973 a Commonwealth Department of Works field party spent a month doing the preliminary investigation for a hydroel6ctric scheme on the Waga River9 a tributary 6f the Kikori Rivero The proposed site is located some 15 km South west of Poroma Patrol Post which is 20 km South of Mendi. Because of the remoteness of the study area9 daily access was from Poroma using a helicopter. As the proposed scheme is located on knowledge of the underground hydrology and any cave systems was vital to the investigation. This work was done over a two week period by Gerry Jacobson (Geolo Survo9 Dept. of Lands) and myself 9 assisted by Bruce Gil tman (Co Do .L) and Banai Triure (Geol. Survey). Probably about 100 caves and small cavities were explored 9 most of which_ were smal1 a . -The longest was an old stream passage 195m-long and generally 2 m tall and up 10 m wide. The stream that formed the cave sometimes passed through it and continued in a series .caves for 500 mo The entire system was not traversed as there were 10 entrances to .the surfaCre which one to avoid muddy tight squeezes. The longest section allowing easy movement was 65 m long. The stream drained a small valley and flowed intn the Waga River. Another cave 40 m lnng takes a stream of 0 o 3 cume-cs ( 10 cusecs) from a very large distributary flowing from the rivero


61 NIUG INI C.A VER VOI1UME 1 NUMBER 3 About eight other caves worth recording were enteied, the longest being 25 m. One cave 14 m long acted as an overflow channel for the river. The most hydrological feature was the distributaries which carried water from the Waga River. One was flowing at 10 cumecs (330 cusecs) -a very high flow rateo (A typical small cave stream flows at 002-0.1 cumecs.) The cave into which the distributary flows must be large, but we dDUld find no way in. Another distribut2ry showed most puzzling behaviour. When we first saw it, it acted as a distributary flowing at 003-.06 cumecs (1-2 cusecs)o There were four channels and all the flow was going into channel number 3. Then on the 12 June after he2vy rainfall four channels were flowing to the river at a rste of 3 cumecs (measured at 94 and 111 cusecs). The flow had reversed overnight. Flow had reduced to 006 cumecs the following day coming out of channels 1 and 2o The following day it WDS again acting as a distributary, that is9 flow had again The next day there were Oo3 cusecs going from the river into channel 3, but with the ac:ded complication that the ':iater was flowing out of channels 1 and 2o Most confusingt There were another two distributaries that flowed at o15o3 cumecs (5-10 cusecs) depending on river level. Measurements in the c7aga River suggested that about 17 cumecs (out of 57 cumecs total flow) were being lost from the river over the study area of a few kilometresp There is reason to doubt our meosuremen howevero The distributaries accounted for much of this loss. _Q_J;'_:hrgs Where all this water goea still an unsolved pro5 .em. 'Ne investiga tea a serie;s of sprinBs a few kilometres West of the study area, but at tbe time there was no flow from themo They must carry very large flows at times from the size of their cbannelso Areas of young regrowth suggest flash floodingo However, the altitude of the springs (1060-1070 m) is ebout the same as the distributaries and these springs more likely drain the limestone plateau at the back of them. The springs occur at the base nf the limestone where the contact with mudstone occurs-0 Along the river in our study area there were about seven springs but combined flow wns only about 015 cumecso Larpe springs were seen at Beaver Falls on the Muli Rivero This is about 40 km from the study areao

Honeycomb karst consists of a surface punctured by solution holes or dolineso With cone karst the dominant feature is a positive formo Rounded cones stand up from a basal surf2ceo Strike ridpes orientated IToWa-S.E. dominate the broad topography in the River areao Honeycomb karst is found on top of these ridges where they are broad enough, and in the valley floors on gently sloping land& In places the dolines were only a few metres deep and apart, suggesting a relatively young 2geo Possibly a mudstone cover has been removed by recently o Generally dolines ;,vere metres deep and aparto J.10 On the l'fobi River a few ki lome t:ces South of the junction of the L1ubi and '.;:aGa ri ve!'s ttiere is a natural bridge through which the river flowso It was estimated as 120 m tall and 200-300 m longo The cave mouth into which the river flows is about 15 m tall and 50 m wide • The most disappointiri.g aspect of the trip was the lack of big caves despite the promise of the area and our resources of time, manpower9 a helicopter and labouro However, the unusual hydrology and interesting karst topography was a good as vvell as the general primitiveness of the area and the peoplea As I spend more time in promising are2s searching for caves in Papua New Guinea, the realiz2tion is coming that extensive and tbict limestone with underground drainage does not necessarily add np to de or long cave;:.:; that one can enter" It is hoped to publish the hydrological and geomorphological data in Jieli_ct_i t8-. with the cave maps o * * *

65 NIUGINI CAVER VOLUME 1 NIDJIBER 3 PAINTINGSo Twenty metres from the entrance there are two adjacent wall paintings done in red and black (see figure). The red colour is derived from red clay. One figure resembles a face and the other is star shapedo They were done on a smooth surface a few metres above floor level. The local villagers said that they "bilong bipo11 -at least before World War II anyway. The paintings indicate that it was prohibited to go inside the cave or drink the water from ito However since the Europeans came (the Patrol Post was established in 1967 only) and have drunk the water, the villagers have also done soo The paintings seem different to me from those described in the literature from the Chimbu7 Kainantu, Port Moresby, Kitava Island (Trobriand Islands), and Jafi and Jegriffi in Irian Jayao FAUN.A'o Ten metres from the main entrance a python was curled up in the ceiling when we visited ito A fish 8 em long was seen and small bats inhabited the entrance chamber9 OTHER IN THE AREA. (Information from John Van Amstel and Jim Wellingtoii") South east of Poroma two caves are known. One is a doline at least 15 m deep whi•h :aas been entered. The other nearby one is small. -Near Nenia North west of an unstable sinkhole is known .. * * * THE CAVING 3CENE Four cavers went over to the Keriake plateau on the West Coast at Eastero They were trying to get to a very large doline therec It appears to be approximately 1200 m by 700 m and 140 m deep (possibly the doline visited by Fred Parker years ago?). The party flew to Torokina on Good Friday morning and walked to Atsinima village that day. However some of the villagers refused to take the party there and nothing could be done. (Information from Hans Meier) Bill Sanders9 Van Watson and Kevan Wilde got down a deep pot ("The Hole11) in the Chimbu at the end of Eastero They pulled out at 170 m depth down before reaching the end of the cave o (See report this number o) .. _ . Gerry and Rae Jacobson and family and a few friends seem the only people caving out of Moresby these days. Over Easter they tried unsuccessfully to find the cave at Javavere mapped by Bob and Viv Vincent (see map this issue)o The Vincents have now gone finish and are off on a world trip.

We then struck an 8 m abseil (wet) which we also rigged with terylene9 this was followed by a short scramble whieh brought us out into a much cleaner area with a .deep fissure. Van tossed the 1'dd reck;dfwn fissure whi•h produced impressive deep hole noises. We that the chasm could well exceed 80 m so we rigged our l•ngest terylene rope of about 75 m with a knot tied in the end. Van off through the narrow opening and exclaimed that it was a beautiful clean and open shafto He ran out of rope whilst the shaft was still going9 but was fortunately carrying a 25 m rope on his back which he tied on to the erig inal with a super-clever type knot and continued the abseil. Kevan and Bill followed Van down the rope and altng a short scramble• We then rigged a short hand-line of about 5 m which "dr8pped" us on to another pitch of 35 m down a series of cascades which we rigged with a No. 4 nylon. Oh yes., I forgot to mention that there was a 5 m ladder pitch after the 5 m pitch nearer the entrance (see sketch)o Two of our wet cells freaked out and Van and Kevan were obliged to use carbides which9 unfortunately9 kept drowning themselveso Van chimneyed down for about 15 m or so and came back witb a report that "The Hole" was still goingo We decided to surface and return before the July-AugustSeptember Southern Highlands District Expedition, to complete the explorationo At the time the decision was made, there was also an cminous rumbling noise rolling up the system which assisted us in making up our minds about leavingo We outj using Jumars and were on the surface by 8.15 p.m. (Progress was hampered by failing carbide lampso) Bill did a great job of hauling the wet ropes out in 'H' frame pack which won loads of admiration from Van and Kevan. In conclusion9 the cave is well worth revisiting and seems to be a definite goer. The drainage for the area, the River Singa, is approximately 400 m below the entrance and the system is still 9oing 1Ni th possibly enough go to exceed the magic fto \Doesn't sound so good in metres.)

IRAPUI CAVE 2 POROL K3CARPMENT 9 CHIMBU DISTRICT • • IC Ao Wilde * With approximately 4 km of surveyed Irapui is the longest cave known to and surveyed by speleologists in Papua New Guinea in July 1973. The cave has not been fully explored •. ,, . 0000000000 "' Irapui is situated approximately 30 m above the ef the Kwiningl Gorge through which flows the often boiling River Kwi. (Ningl being the Kuman term for water .. ) The Kwi itself runs on the northern side of the Porol Ranges (Escarpment) in the Chimbu Districto The initial tion was made in 1964 but it was not until May 1972 that a and survey was made. Frem Kundiawa it is possible to reach Irapui by a shert drive and a relatively short walk, the total time being under one and a half hours. The drive takes one along .the East side of the River Chimbu along the road that leads to Mai which lies behind the Porol Escarpment, an almost majestie knife edge ridge that travels from Kundiawa to Chuave split by a g•rge through which flows the River Chimbu, a shallow but fast river. The first few miles of the journey are a little bumpy but a most pleasureable drive with almost bare magnificent limestone cliffs falling away into the River Chimbu.. The road has two hairpin bends that must be negotiated and it is strongly recommended that a four wheel drive vehicle be used. Vfuen one arrives at the highest point on the road9 it is a good idea to stop and take in the scenery from one of the limestone outcropso Below is the boiling River Kwi which flows into the River Chirnbu and through the mighty 'V' that the Chirnbu River has cut through the escarpment o Above9 the rock-strewn Porol Escarpment climbs towards the sky. A short drive further on, after the road swings to the right1 brings one to a small native track that descends to the River Kwi. This is the track that leads to Irapuio A twenty to thirty minute walk along this track which follows the river then ascends a little is the entrance to the As a point of interest there is a cave in the limestone-ut crop at the beginning of the track; this is not Irapui but Mebikumbago9 a long straight system with two levelso * P.Oa Boroko, Papua New Guineao


71 NIUGINI CAVER VOLUME 1 NUMBER 3 The entrance to Irapcri is approximately 2 m in diameter and leads down on to a 45 mud slope and into a small chamber. Leading North west from this chamber an old passage 40 m long which closes off o There is a 45 slope upwards gouth west with a short squeeze which leads down another 45 slope (muddy) into a small chamber which contains a large fallen slab of rock& The route travels along the right hand side of the rock, although it is possible to go over the top. This leads into the first chamber known as Marata chamber (see (1) on map)o The distance covered so far is approximately 100 m. Marata chamber is named after a stalactite which resembles the fruit of the pandanus palm that the natives call maratae The chamber is 50 m long and 20 m wideo In the North east upper corner of this chamber is a further chamber known as Goga-Kuri chamber (5) which develops into a passage, the whole being 150 m longo This passage contains the first indication of good 'living' formation. In the southern upper corner is a shaft 25 m deep (2); known as Irapui-Kombago. It is made up of loose conglomeratec There is an excellent belay point from a column which has conveniently formed on the side of the shafto Each of our descents have been made on single ropes with aid of abseiling racks and Jumars9 however7 it is a perfect pitch for a laddero At the bottom of this shaft is the river passage known as the Kwiningl Overflow (4) which is some 300 m long and travels in a south westerly directiono The stream terminates in a whirlpool sink in the chamber known as Skunge (7)9 named after the incredibly slippy thick mudo This in turn joins up with Tarn Chamber (11)o The river passage is clean of weto Approximately halfway along is the chamber called Ples Pit-pit (6) .. The continuation of the original passage which leads off Marata chamber also takes one to Tarn chambero Along this passage which leads to the base camp (20) is good formation in the form of flowstone, and stalagmites etco The base camp is 150 m from the chambero The vertical squeeze on the right before the camp leads nowhereo The base camp is a raised sandy platform which is perfect for overnight trips .. This entire passage which continues for almost the total length of the cave is probably the original stream passage and now makes up the upper level of the systemo After the base camp the passage continues in a north westerly direction. Just past the base camp travelling due South is another passage some 30 m long which leads to the Balcony (10) which is an overhung 8 m pitcho It is recommended that this pitch be tackled by ladder, it being most unsuitable for the single rope techniqueo There are two

There are higher levels along this passage that have not been explored with the exception of UppE;rsoxploration which is situated on the left of the river passage when it finally terminates in a sump .. A little should be said o.bout the Kwiningl Overflow (4) and the subsequent river pass e that leads to Skunge (7),, Beneath the shaft Irapui-Kornbogo is a small chamber through which flows the river passageo The overflow which leads off the chamber in a north easterly direction begins in a number of ducks vvi th as little as 0 o 1 m airspace an,d. af::ttjr about 30 m opens up. On one occasion at the time of the survey the water level rose and subsided 5 m in twelve hours! The resulting danger is obvious and little needs to be said. One must always be rnnare of constant danger that is caused by tropical rain storms. Throughout this system is some excellent formation, and although little has been said during the description9 it is well worth noting that apart from The Passage of a Thousand Wounds (9) and (13) there are varying types of formation present in just about every major passage and chamber with the exception of the entrance area which is dry and 'dead' e Although the system has been explored and surveyed, there are many opportunities for further exploration and the system is a rewarding tripo The survey took three days from the base carnpo However9 the system could probably be done in two days without the hindrance of taking bearings and There is approximately 3000 m of known passage in Irapui. The survey was carried out in May 1972 at which time little of the cave had been fully explored.


75 NIUGINI CAVER VOLUME 1 NUMBER 3 LONGEST CAVES IN THE WORLD After years of patient work by American cavers, the connection has finally been made between Mammoth Cave and Flint Ridge. The resulting system has a surveyed length of 230 km, which establishes it without any doubt as the world's longest to datea The connection was made on September 9, 1972a Low water conditions allowed cavers to explore a 1830 m long crawl/stoopway which provided the long sought for linko Throughout the years9 a rivalry has existed between the cavers working in Mammoth and their Swiss counterparts in HBlloch. The Americans would announce a new record figure of surveyed passages9 only to receive a telegram from the Swiss telling them of discoveries in HBlloch which brought the laurels back to their pet systemo But as the Americans pieced together the Flint Ridge system from Crystal Cave, Unknown Cave, Salts Cave and Colossal Cave9 their explorations took them nearer and nearer to the daddy of them all, Mammoth. Rumours persisted of only a matter of metres separating the two under the intervening Houchins Valley, but the connection proved Now that connection has been made, and the ]/Iammoth/Flint Ridge system surveyed length has probably a long way still to go even if no further discoveries are made -which is unlikely -for the backlog of discovered but unsurveyed passage is higho (Reprinted from Descent No. 23 p. 24) Hl:Hloch in Switzerland with about 115 km of surveyed passage is quite definitely namba tu in length nowo With 54 km of surveyed passage9 the Optimistitscheskaya gypsum cave (say that in the Ukraine comes in as the third longest in the world and the longest in the UoSoSoRo Australia's longest is Exit cave South of Hobart in Tasmania with 17 km of surveyed passageo Irapui with its 4 km up in the Chimbu still has a little way to goo Wet pastaim! * * -*

The bottom is 6 m x 9 m, the floor clogged with mud. Two other holes about 45 m deep were seen but both seemed to endo Dolines the Fikombaro roado Two of these dolines were examined 9 but b"oth we-re clogged 9 the water escaping by seepageo About 75 m above the road a horizontal entrance in the cliff was entered and followed for 60 m. The entrance is 9 m x 6 m, the floor flat and level. Inside the floor is broken, and the passage becomes steeper still, ending in a rear vertical clay wall. There is river gravel on the floor at this point9 and a trickle of water falls from a high narrow cavern aboveo The clay wall is toe dangerous to climb, and exploration was abandoned9 Beside the entrance is a 1.5 m x 5 m hole which is reported to be quite deepo COlVIB![ENTS The party was very disappointed with the horizontal cave described aboveo It seems that a cave is considered in relation to others close by when being described by a villager., In an area with no caves a 5 m long passage will be described as 11big". So far9 ten promising vertical holes have been examinedj and all found to end from 30-45 m downc The reason for this could be the very thick soil overlying the limestone -over 15 m in places, together with the high rainfall. There are very few real outcrops on the back slopes of Elimbari which is unfortunate9 because a really solid outcrop would avoid the soil problemo About a dozen holes were seen9 but by the law averages, it would be safe to assume that they would be cloggedo Perhaps the best idea would be to look for outcrops, or areas Jf local folding9 where the rock is exposed. Such areas may exist tovvard the summit of Mount Elimbari, but very little was seen on the backslopes. No jointing or bedding could be discerned, but in places small vertically weathered outcrops were seen. The best idea would be thorough exploration below Fikombaro Oriri and Leyer Rivers.

A second passage leads from the North end of the main chamber9 and terminated in a sheer drop (fissure)o Stones took from 4-7 seconds to stop bounc ingo This could be a more direct entry to the rivero I consider this cave the most d2ngerous in Chuave, both from flooding9 and a party becoming losto Great care should be taken in both regards, and adequate light thorough exploration of the lower levels9 in particular the second passageo Sixty metr2s to the North is a huge cave 45 m deep, steep sided9 60 m across9 and the bottom filled with mud o The villac;ers seemed sure thc::t the tv,;o caverns joined. , During the twenty-four hours, goodwill was found everywhereo I told that I had now seen all the caves in the area, and no objection made to my entering any cave 9 and I was told of tvJo more small streams going down dolines between "Noo 811 and "The Pit" -the people have always denied any caves hereo They were pleRsed when I told them that hordes of Europeans would not followo It was agreed that (identified by trog suits) would be given full freedom in the area. B 1 th 0 . ;inl. n .. l' . d . t . . e ow e riro a oI ao ines, in ica ion is that this is tbe river th,::. t joins the Topia near "No o 8". This makes Oriro cave a part of Kirn.01109 only 5 km away1 and nearly 300 m bighero When exact figures are established? and a thorough trip made, a record could be claimed. The Leyer river does exist; only two small streams which flow into small toleso These streams could join Topia, but probably above groundo

NIUGINI CAVER VO.LUME 1 NUMBER 3 88 Hidden behind boulders and screened by vegetation the sizeable opening is sometimes difficult to find. The cave goes straight into the cliff o Inside the entrance is a large circular pit into which the efflux pours during the 'wet' season. A single passage leads up to a rock slope which must form a waterfall when the stream is active. At the base is a deep scour. Above the."waterfall" the passage enters a chamber largely filled with a huge slab of rock. Around the left side of this rook the passage flattens out until it is too small to follew. It is through the smaller openings here that water enters the active oortion of this cave. There was no flow when the cave in April 1973. Stalactite and stalagmite formation occurs in this area and above the boulder fill. A climb over boulders to the right gave entrance to a large tunnel leading back in the direction of the cliff face. This emerged into a large chamber which could only dimly be made out in the torch light. Our intrusion aroused the large bat population which started a migration to more remote corners of the cave. Some flew into an opening above the tunnel and closer inspection revealed that this most likely led to another opening on the surface of the plateau above. A scaling ladder would be necessary to climb this opening. The chamber is partially filled with fallen boulders, the domed arching high overhead. The floor was covered by a thick layer of fresh guano. From here a large passageway led to another chamber which also housed batsc The slope of the cave had been upwards and this second large chamber was not far below the surfaceo A cluster of tree roots emerged from the roof and hung down for some 7 m into the cavity. After clambering upwards over large fallen boulders and through several smaller chambers, emergence to the surface was finally gained. This top entrance occurred at the bottom of a conical shaped doline, approximately 20 m deep. The surface around the doline is covered with low bush which tends to conceal it from the main road only 100 m or so distant. During the visit to this cave in April, 1973, by Chris Rawlings and myself, no collecting was done in spite of the rich cave fauna that occurred. In addition to the bats and insects associated with them and with the guano, cave spiders and cave centipedes were particularly noted. These warrant collection and further study.
