But not Don Broussard and John Fish. Both were supposedly sane cavers, but after the recent incident in Tinaja one begins to wonder.Asevidenced by the report below, one never knows what to expect.Forthis reason, cavers should refrain from plunging into any water filled passage unless the most sophisticated diving equipmentisin use and, most important, the persons involved areexperienced.ACCIDENT REPORT NEAR DROWNING IN SOTANO DE LA TINAJAastold to Ronnie Fieseler by Don Broussard and John Fish About 1 July 1972 a groupofcavers entered S6tano delaTinaja for the purposeofpushing a siphon in an attempttoconnect the cave with S6tano del Arroyo. At the siphon, Don Broussard prepared to enter the water.Hewaswearing a diving mask and had a flash light tiedtohis waist. A safety linewasalso tied to his waist and hewasto be belayed by John Fish. Don entered the siphon and after swimming a short distance came to an air pocket where he took 3 to 4 deep breaths. Evidently, the pocket contained very little oxygen and a high concentrationofcarbon dioxide and Don passed out. John Fish and otherssawthe light from the flashlight sinking to the bottom and rapidly pulled Don outofthe water. At the edgeofthe siphon Don showed no signsofbreathing. Acting rapidly, the cavers present lifted Don upside down and poured wateroutofhim. Pounding produced a large amount.Hewasthen given artificial respiration until he began to cough. After coughing up more water Don slowly began to regain normal breathing and the group exited the cave after Don had recovered sufficiently. After a day's rest Donwashis normal self except for very bloodshot eyes, which have since then improved. Thisisessentially the story told tomewhile Iwasin Cd. Valles, shortly after the accident.

Date: November 1971 Destination:CavessouthofMicos(MunicipiodeValles) and cavesinthe vicinityofCarta brancha1 (Municipio de Jaumave) Location: SMa, Tamasopo Region-Micos, Morita, Otates andMinasViejas areas, Sierra de Guatemala Region, Cartabrancha1 Area. Persons:DavidMcKenzie andBillRussell Reported by:BillRussell The group returning from Tres Manantia1es metDavidMcKenzie at the Hotel Mante. That night David andBillRussell drove south toward the villageofMicos, about 20 kNWofCd.Valles, to visit a blind fish cave previously investigated by the German biologist Horst Wilkins. This cave had originally been located by biologists from the joint Mexican-American Vampire Control program. The ownerofthe Don Tomas ranch atMicoshad tolduson an earlier visit that the fish cavewaslocated at the endofa mountain ten miles southwestofMicos,sowedrove to a small ranch near the endofthe mountain and asked about thecave.The cave proved to be well-known and a guidewassoon obtained who ledusto the Horst Wilkins fish cave,aswellastwo other smallercavesnearby. The next two days were spent mapping thecave(named by the Germans Cueva del Rio Subterraneo) and investigating the other nearbycaves.Cueva del Rio Subtemineo proved to be 1230 feet long and divided into two sections, oneofwhich may continue. Thecaveislocated at the endofa long arroyo that drains about ten km2ofthe swampy valley to the eastofthecave.The main sectionofthecaveisentered by climbing down over breakdown at the endofthe arroyo. The upper section

This tunnelis20fthigh and15ftwide and ends in a 30-foot pit.Wecrossed the pit by lassoing a formation on the far sideofthe pit, but 50ftfurther onwasanother 30-foot pit thatwecould not cross.Wecould see a passage continuing on the other side. The passage lead ingtothe main cave goes steeply down over large breakdown to a depthof70ft,where thereisa temporary siphon that blocks access to the cave during wet weather. Beyond this smallsectionofcave, a steep slopeofwashed and rounded cobbles leads up to a larger horizontal passage.This passage ends in a 10 foot climbable drop into the river passage. Here a stream flowing about 20 gpmwasencountered, probably derived mostly from the surface arroyo that sinksbefore the cave entrance. The stream passage can be followed through waist-deep pools to a large room 100ftlong, 40ftwide and 30 ft high. The stream crosses this room and siphons just be yond, 95ftbelow the entrance. From this room, 30 ft above the siphon level, a passage scoured by flood waters leads to a second room 240 ft long, 40ftwide, and 30 ft high. A short passage leads from this room and ends in a second siphon. Both siphon pools contain numerous blind fish, and some blind fishaswellaseyed fish are present in the stream. After returning to Austin itwasdiscovered that the cave had been visited three days before by another Austin caving group. (See trip report byGBEnquist, Gregg Thompson, etc.) Another cave about one km to the westofCueva delRioSubtemineo proved to be a small shelter with a passage at the back leading steeply down to water. This cave, named by us, Cueva del Lienzo, also containedbotheyed and eyeless fish.Wewere also shown acaveone mile to the eastofCueva delRioSubterraneo at the endofa small arroyo. By climbing over breakdown and then descending a IS-foot vertical drop,wereached one endofa long stream passage from 4 to10fthigh, with several rooms. This passagewasfollowed for about 1000ftto where the airbecame so poor (probablyCO2),that explorationwasabandoned. The cave, namedbyusCueva de Otates, containednotonly blind and eyed fish,butnumerous crossbreeds with partially developed eyes. From the Micos areawedrove north on the dry-weather-only road leading west and then north from Micos along theRioNaranjo, toward the townofEINaranjoonhighway 80 westofAntiguo Morelos. Just southofEIEstribo Arch, a road leads across theRioNaranjo and south to Quinientos and from there back to Micos. Six and a half miles from the arch a side road leads west into the foothills to the villageofMinas Viejas. Hereweasked about caves and were led to several caves near town and were told,asusual,oflarge caves high in the mountains. One pitwedid visitwasnear a beautiful 100 ft waterfall, about ten minutes walk from the road. The Minas Viejas areaispromising, but apparently it would take several days on foot to reach large caves and returntoMinas Viejas. From Minas Viejas Dave and I drove north through Mante and then to Encino, the Gateway to the Sierra de Guatemala.Wehad heardofa large deep pit in the northern Sierra de Guatemala, and planned to walk to Cartabranchal, the only inhabited place in the northern halfofthe range. On a previous trip I had walkednorthalong the road that followed theRioSabinas valley. This road leads north from the west endofthe low water bridge westofEncino, goesbythe Nacimi ento delRioFrio, 300 m northeastofthe villageofLaPuerta, through Ejido El Encinito (calledLaFlor), and ends at San PedroLaColina. From here a trail leads up to the VillageofMonte Cristo, and from Monte Cristo an abandoned trail zig-zags up the faceofthe range for about 2000 ft vertically to the abandoned lumber campofMonte Carlo, now only an overgrown clearing.Monte Carlowasthe furthest point north cavers had previously reached in the Sierra de Guatemala and with David's Blazerweplanned to driveasfar as possible along the old road that leads to Monte Carlo. This road leads north from Julillo,sowedrove west from Encino across theRioSabinas and up the steep east slopeofthe Sierra to Julillo. Hereweturned north and

Alejandro Prieto in his book,HistoriayEstadz'sticadel Estado delTamaulipas,describes his explorationofa cave at the nacimiento in 1860as"going through two or three feetofwater for 20 meters to where itwastoo dark to proceed farther." Thiswasapparently upstream in the main nacimiento. Cueva de los F6siles (44)isprimarily a large room from which much fill has been removed for its mineral content. From this entrance room a side passage leads to a skylight. This caveisreportedtobe about 1 miSWofthe nacimiento. At the same approximate location a cave ope ningwasseen from the air at the baseofa cliff on the east faceofthe range. Also a small cave (61) about one-half mileSWofthe nacimientowasreportedtolead downward to a siphon after about 100 ft. Cueva delasColmenas (22) extends west from an impressive sink about 400 ydsSWofQuinteroonthe flat topofthe range. The entrance sinkisabout 200 ft long, 100 ft wide, and 60 ft deep, but can be entered down a breakdown slope. From the sink a steep slope leads downward to a horizontal passage extending for about 300 ft through several crawlways. Near the endofthis passage a small squeeze to the right leads to a pit over 200 ft deep,asyet un descended. Another sink (24), somewhat smaller than the Colmenas sink was seen from the air about 200 m to theSW.A small climbable sink (23) 100 m NEofthe Colmenas sinkwasexplored downward for about25ftto where a rock blocked the topofa 25-foot pit. The range above Quinteroisspotted with sinks and pits. Alejandro Prieto, who laidoutthe villageofQuintero in 1860, reported finding a pit above the villageofQuintero in which rocks fell for12sec (probably not free) until they produced a sharp crack "like a body opening a way into the water." Grutas de Quintero (84)islocated about 2 km by road southofthe townofQuintero, where a stone stairway leads to the entrance. The frequently visited main partofthe cave consistsofa spacious passage 30 ft wide and 20 to 40 ft high. Immediately inside the ent rance the passage divides and rejoins after 300 ft just before a skylight. Beyond the skylight the passage continues for 1450 ft to a 30-foot pit. This sectionofthe cave contains numerous travertine dams and several short side passages leading to pools. Throughout this area phos phate miners have dug pits and built trails, and the operations have damaged manyofthe travertine dams. Beyond the pitisa short wet passage, which enlarges to10ftwide and 8 ft high and continues past a right fork for 2000 ft to a flowstone mass that almost blocks the passage. A hole too small to traverse continues. The right fork leads to an almost unclimbable 8-foot wall and extends for 650 ft to a small pitasyet unexplored. Cueva de San Lazaro (94)isa walking size tunnel in the north sideofan arroyo about 1 km NofCueva delaFlorida. The tunnel jogs right after about 200 ft and ends in a flow stone block. The entranceofthe caveisabout 20 ft above an arroyo and the cave follows the strikeofthe steeply dipping beds along the west flankofthe El Abra anticline. Cueva delaFlorida (43)islocated 1 mi Nofthe villageofEl Pach6n, on the west slopeofthe El Abra Range. Just inside the entrance the cave divides into almost separate systems. The right-hand tunnelisa sinuous passage averaging10ftwide and15ft high. Thereisone major side passage and several interconnections, and a crawlway that leads to a blind 60 foot pit. The main right-hand passage ends in a steep upward slopeofflowstone, and above this a small water-crawl extends for several hundred feet. The larger left-hand tunnel leads through several rooms, the innermost containing numerous bats, and finally comes to a slope leading downtoa poolofliquid guano. Beyond the poolisa steep climb over flowstone and the passage ends in an unclimbed dome. A few hundred feet down the left-hand tunnel from the entrance a tortuous passage, mostlyofcrawlway size, leads to a small entrance on the sideofan arroyo.

Cueva deEIPach6n (76)isan 800-foot long cave above the village well at the south edgeofthe villageofE1Pach6n. The cave has also been called Cueva delaCampana after a forma tion at the endofthe cave that rings like a bell. From just inside the entrance a mud-floored passage 20 ft wide and from 8to16ft high extends for 600 ft to a lake 100 ft long. The cave ends beyond the lake in a mud slope. Water apparently flows from the cave after heavy rains. Cueva de El Abra(l)isa large frequently-visited cave andisvisible from Highway 85 in theElAbra passSWofCd. Mante.

Cueva Chica de Arroyo Seco(l01)islocated westofthe Ejido Felipe Angeles at the baseofthe range just above a permanent pool at the headofthe normally dry Arroyo Seco. The cave entranceisabout 20 ft above normal pool level and floodwater at times apparently flows from both the pool and the cave. The caveis15fthigh, 20 ft wide, and about 200ftlong. Toward the back the cave narrows and two fissures lead down to water at about pool level. Cueva Grande de Arroyo Seco(l02)islocated about 100ftabove and slightlynorthofCueva Chica de Arroyo Seco. Its inconspicuous entrance leads to a room 20 ft high and 40 ft in diameter. Two fissures lead from this room: one goes over a handline drop to a deep pool, and the other extends 250 ft to a pool formed along a seriesofparallel fissures, some partially dissolved partitions rising like knife edged icebergs from the lake. A small 40-foot pit (111 ) to water exists near the Nacimientoofthe Rio Tantoan, and about 3 km southofthe Rio Tantoan, Cueva del Arroyo Secoislocated at the headofanother normally dry arroyo. This caveislocally reported to be long but, it has been visited only when the arroyowasflowing andany possible passages were blocked by high water. La Gavia Area: The high, relatively flat crestofthe range from 5 km southoftheEIAbra pass to near the San Luis Potosi Tamaulipas state line. This large areaispoorly known, with only the large sink,LaCaldera (6) having been visited. La Calderais1200 ft long, 300 ft wide, and 200 ft deep with nearly vertical walls except toward the south where itisdeeply undercut. Crawlways lead to about 300 ftofsmall cave. About 2 km northofthe Calderaisa pit seen only from the air. This pit (80) appears to drop about 200 fttoa vine-covered floor. La Noria Area: The western slopeofthe range from eastofAntigua Morelos to the San Luis Potosi Tamaulipas state line. Cueva de Santa Elena (99)islocated at the west edgeofthe El Abra Limestone out crop and has a large, shelter-like entrance, one endofa once larger room. A crawlway spirals downward from this room to a 20-foot drop into a dome room. Beyond the dome room are two 30-foot drops, the last dropping into a large room over 200 ft long and per haps 100 ft high. Mudbanks indicate this room floods,butitispossible to squeeze down

This hole eventually drops into a fissure passage thatisseveral thousand feet long. At some points itispossible to chimney downtodeep water. From thebottomofthe main entrance pit passages lead to a maze level with several thousand feetoflow rooms and interconnecting crawlways. Several pits drop from the maze level into unsurveyed lower levels where long stream passages are reported. More than 10,000 ftofpassage have been surveyed, and no surveys have yet reached the loweststream level. Los Sabinos Area: The west slopeofthe range from eastofK 19 northofCiudad Valles,tonear the power line NEofCd. Valles. S6tano del Tigre (114)isnow approachable by a rough roadthatpasses within a hundred metersofthe entrance. The 265-foot entrance dropislocated at the endofan arroyoabout2 km longthathas cut down to theElAbra Limestone through the overlying non-cavernous rock.

Here a passage turns right200fttoa 30-foot drop into the Ricinuleid Passage, an upstream silt-floored passage about 1000 ft long inhabited by a large colonyofricinuleids, rare tick-like arachnids relatively common in the Sierra deE1Abra. A complexofpassages interconnect the entrance pit and the ricinuleid junction. From this area the main downstream passage extends firstasa high fissure,thencontinues through shallow watertoa lake 800ftlong with ceiling heightsofonly a few feet. This passage finally ends in a large mud-banked terminal siphon room. S6tano delaRoca (91)islocated just above the arroyo bed, downstream from a large boulder inthemain arroyo eastofthe villageofLos Sabinos. The pit receives water only during major floods. A 10-foot drop leads into a small dirt-floored room, where a small hole opens into a 120-foot pit.Atthebottoma muddy fissure drops 8 ft into a small but promising crawlway with air flow.

The endsofmajor passages in Arroyo line up with major passages in Tinaja, and a strong air flow toward Tinaja indicates a physical connection. The 50-foot entrance drop into S6tano del Arroyoisreached by a short handline drop in the arroyo bed. The entranceisessentially a large slot about 150 ft deep except where the arroyo enters. The main passage from the entrance slot goes several hundred feet to a junction. Here a long water passage circlestothe right and eventually connects with the entrance, 30ftbelow the arroyo. The main passage continues over two 40-foot drops, the last into a triangular room with a lake at the far corner. From thebottomofthe drop into the triangle room a fissure leads up into a passage that extends almosttoCueva de Los Sabinos,butends in a pool before connecting. Across the lake at the low endofthe triangle room a passage leads to a 30-foot drop into a pool. Beyond this pool several thousand feetofpassage trend south and almost intersect passagesin S6tano delaTinaja. Several passages end in siphons or breakdown and flowstone blocks, but some drop into a large lower level passage that has not been explored due to high levelsofCO2caused by decaying debris brought in by floods. Above S6tano del Arroyo an unnamed 70-foot pit (103) has been located near the entrance. Cueva de los Sabinos (93)isentered through a 100-foot high, 50-foot wide entrance in the sideofa large sink 700 m eastofthe S6tano del Arroyo. No water flows into this opening. From the entrance a steep breakdown slope leads to a junction. From the junction area several smaller passages continue along parallel fissures, but the main passage goes 400 ft toward the north and also back to the left under the entrance, where thereisa ladder leading to the lower level. Below the ladderthepassage enlarges to 40 ft wide,20 ft high, and extends toward S6 tan a del Arroyo, ending in a siphon. Two hundred feet from S6tano del Arroyo extensive water passages at this level also siphon. S6tanodela Tinaja (115) can be entered without equipment, by climbing over rocks and ledges in the arroyo. The main passages in Tinaja form a rough square. The entrance passage trends east for about 1500 ft to a 30-foot drop into the Sandy-Floored Passage, which averages 30 ft wide andIOta15ft high. This passage trends generally north for 2000 ft to the Lake Passage, which continues west for 1000 ft more. From the entrance a water crawl leads north almost to the lake passage. A downstream passage carries floodwater from the south endofthe Sandy-Floored Passage over a seriesofdrops and obstructions to a large, deep siphon. Passages from S6tano del Arroyo extend into the area between the lake passage and the water crawl and strong air currents indicate the likelihoodofa connection. Up the arroyo a few hundred feet from the entrancetoS6tano delaTinajaisa waterfall, partofwhose water by-passes the falls by meansofa short cave (116), and further upstreamisa pit in the arroyo (117) now plugged at 30 ft. A pit (119) with a probable passagewasdiscovered above Tinaja, and in returning to it a blind 1 50-foot pit (118)waslocated. Farther awayisanother blind pit (15). S6tanodeSoyate (104)islocated 500 m southofthe road to Cueva Pinta. The entranceis50 by 20 ft and the pit drops vertically 646 ft, slightly inclined to the vertical,sothatdescentisagainst the wall. A fissure leads from the bottomofthe pit to a 35-foot drop to a ledge overlooking a large lake. The lakeis400 ft long and 100 ft wide, andis173 ft deep at normal water level. From the ledge itisnormally a 35-foot drop into the water (only 135ftdeep at this point),butafter heavy rains the water level rises above the ledge. South along the trail past SoyateisS6tano del Largarto (54), a 180-foot fissure located just westofthe trail. Cueva Escondida (38)isreached by a short road leading north from the Cueva Pinta road. The cave has several hundred feetofrooms and small passages that have been mined for nitrates. Eastofthe Cueva Escondida turnoff are two small pits within10ftofthe road, one to the south (40) and one to the north (39). Both might be pushed with effort.

The Sotanito forms the largest partofthe system andisentered through a11O-foot pit half-hidden under a large rock in the bedofthe arroyo upstream from the Pechojumo entrance. From thebottomofthe Sotanito a passage 10 ft wide and 20 ft high goes 400 ft to a complex T-intersection. To the rightisa half-mileofsinuous lake passage some 40 ft wide and 5 to 20 ft high, whichisdry at first, but gradually the water deepens and the passage finally ends in a siphon. This siphonisonly a few ft long and during low water, voice and light communication are possible from this pointtoPechojumo passage. Left from the T-intersection up a flowstone bank, a passage 20 ft long and 30 ft high leads to a chimney and a 100-foot drop into a smaller passage,which enlarges and finally drops into a canyon 50 ft wide, 150 ft high, and 200 ft long. A small squeeze crawl leadstoa 60-foot drop into water from a slot in the ceilingofa room 100 by 160 ft. A flowing stream can be followed upstream from this room through large rooms to a siphon. The Pechojumo entranceis60 by 40 ft, and 45 ft deeponthe arroyo side,butmuch higher elsewhere. Back under the arroyo on the upper level a right fork leads to a mud siphon, and the two left forks form a loop that almost connects with the downstream passage in the Sotanito. From the downstream sideofthe Pechojumo entrance a large passage slopes downward to a 140-foot pit. From the bottom the Lake Passage, 40 ft wide and 10 to 20 ft high, goes 1100 ft to a division. Both passages eventually drop into a high canyon 200 ft long ending in a deep siphon. Beside the trail leading north by the Sotanito in a flat sheetoflime stoneisthe small pit, S6tano deLaLajita (55), a 20-foot drop into a small room. In the sideofthe arroyo between the Sotanito and the Pechojumo entranceisthe11O-foot long Cueva de Le6n (56), a good dry camping place, and near the SotanitoisCueva delasRatas (89). S6tano de Jos (53)isanother opening in the bottomofan arroyo, the pit apparently taking all the water even during large floods. The caveisessentially one large fissure. A 100-foot entrance dropisfollowed by an offset through a hole into the topofa 120-foot fissure. This fissure averages about 50 ft high and10ftwide, being at one point partially blocked by flow stone. At the end the fissure widens and a short drop leads to a siphon pool. The caveisphotogenic, with shallow pools and clean walls. S6tano delasPiedras (80)islocated at the endofthe now abandoned sectionofthe arroyo downstream from S6tano de Jos.A 60-foot drop leadstoa large passage, which ends in a 90-foot drop into a smaller passage leading to a lake. Extending from the lake, a passage 30 ft high by 30 ft wide ends in a siphon. The southmostoftheLos Sabinos caves, S6tano de Palma Seca (78),isat the endofa now aban doned arroyothatno longer carries water, since the rainfall sinks into cracks. A 100-foot entrance pit enters one endofa mud-banked room 150ftlong and 30 ft high. Thereisone side passage 300ftlong. Los Monos Area: The relatively flat, central portionofthe range from eastofK 25 to near the powerline which runs NE from Valles to Cementos Anahuac. S6tano del Loro (57)islocated on the topofthe range westofthe southern boundary. The entrance to this caveis40 by 100ftand drops 195ftto a small talus slope, which leads to a room 80ftwide and60 ft high. From this room a passage extendsNWfor 700ft,gently rising and ending in a flowstone plug. The caveiswell-decorated. Hoya deZimap{m(128)isjust westofS6tano de Loro. The entrance, located at the endofa large sink,is30fthigh and 100ftwide, with a 60-foot cliff above the entrance. A breakdown slope leads into the ent rance room, 100fthigh, 100ftwide, and 250 ft long. A large column partly blocks the passage, after which it opens up to 100 by 100 ft. The next column completely blocks the passage except for a small water-scoured hole leading to a1 54-foot drop, after which a steep breakdown slope leads to a flowstone cascade sloping steeply to a 270-foot drop.
