We walked carefully around understand the layout of the cavern before me. them as we proceeded along the mostly level ground. What I was climbing down into was like the bottom of a bubble, a huge bowl shaped hole in the earth, half of it was covered, creating the huge cavern that we climbed into. I had just climbed down the side of the bowl that was not covered. Inside the cavern there were multiple caverns leading away. Also higher up on the surrounding cliffs other cave mouths could be seen, but they were far too high for us to get to today, and it was uncertain if they actually created real caves I walked into the back of the enormous cavern which had a large pile of rocks on one side. On the other side was a huge slope of snow, one part of which we had climbed down. I wandered over to where a few of my friends stood at the back of the cavern. We have two leaders of our new caving group; Kevin and Carlene Allred. Carlene had helped us rappel The floor slanted uphill and we saw a glow of down the slope to get to the cave, and she sunlight ahead. Switching off our lights we gazed up remained at the top to help people back up. Kevin was at a jagged scratch through the rock that revealed a in the cave with us. By the time I got down he was glimpse of the gray sky. Some snow and a log lay frozen a l re a d y l e a d i n g a g r o u p i n t h r o u g h t h e under the patch of sky, and ther e was no further main cave. So the remaining five of us wandered passages for us to fit through. We made our way back through the smaller cavern. to the light of the large cavern, my friend Olivia being It was a large, breezy hole, with a jam of frozen my model as I took pictures of the large, intricate logs at the entrance. Icicles hung from the opening, structures of ice on the walls, and other cool rock formations. Back in the main entrance we now looked for more caves to explore. The other side of the cavern was dotted by small entrances and we explored around, but none but one led farther than 15-20 ft. One ended at a low pool, inside of which was almost a perfect square of deeper water, and also an ugly scratching of some guysÂ’ name in the soft cave rock beside the pool. We now ventured into the only r emaining long passage, crawling quick ly in our excitement. It narrowed down to end at a trickle of water and some awesome rock formations. Unable to find further, deeper caves inside the passage, we returned to the surface. I was wondering where the other group had gotten off to, as we were unable to find them. W e didn't wait long before the other group returned,

Now there were two sets of twins who joined in this feat In the rainy greyness towards the winters end, Rachel and Rebecca are such a wonderful treat! The slushy snow of the Southeast Alaska season still tends Naturally considerate and thoughtful they are never at a loss To randomly fall and clump around When jumping into icy water they are boss! A few birds occasionally will sound They have lovely blond hair, one has slightly shorter locks But still, one source of happiness is found Their bright blue eyes, slim figures and they are very smart! It clings to the youth just now from school unbound Though similar looking their personalities show them apart They disperse into countless adventures far and wide But a certain group is called to seek out new territory with a guide A girl of brown tresses, with curly, long eye-lashes They go to a land where they can find caves Was the older sister of the twins, she dashes They travel across rough road and sea waves Into any available adventure or sport They seek wild thrills and explorations A brave girl from the farmland in North Dakota she's the sort To gain some experience and see some awesome cave formations She knows all about animals, horses and sheep She's so nice and friendly, open and deep They gathered to embark before a mighty ship With much confusion and stress they managed to slip A traveler by practice, musician and teacher by trade Their massive packs and bags into the three cars He's adventurous and loves hiking and for kayaking he is made! And hurriedly rushed to board the barge. He's kind, energetic, quite wise and strong Now a three hour voyage lay before And can sing and dance all night long! So I messed around with my friends and I'll now describe them some more. He's searching the world for society's reasons He believes in intuition, and is gone with the season. We had an exceptional leader, he's been over the world to every cool cave This awesome spelunker's experience and knowledge is something we crave Another companion on this wild foray He lives for adventure and exploring the earthÂ’s hidden pores He goes by Matty to me, but I suppose he'd rather I say He's fun-loving and kind and has taught us about caving, Matt, Matthew, an amazing nice, great guy! opened our mindsÂ’ doors. He's probably better at you at juggling or trombone, challenge him!, just try! Another comrade that is totally tight Always energetic and smiling as he learns skills, and IÂ’m SheÂ’s wonderfully crazy, awesome and rarely full of spite Gunna call him a brother since we beat each other up all the time! She loves to be random, wild and weird Her nameÂ’s Olivia, one not to so greatly feared This is just half of the crew that came on those treks She's ever kind and nice to everyone she meets to explore the caves and risk their necks She's a high school student who doesn't believe in eating any kinda meats!

Everyone but Kevin was still waiting to climb time slipped through a narrow entrance I hadn't noticed out of the narrow passage, and as I sat in the dark on our first exploration of the tunnel.

As I wandered around with the others, some of us climbed up above a passage way, and finding a deeper, skinny tunnel we edged our way along, walking sideways. It was Kevin who came to realize he had never been here before. W e continued, totally excited to be exploring a new passage. After a few minutes along this un-mapped passageway we came to a drop-off, some water flowing at least ten feet down the sloping floor. We looked around, seeing that the cave continued deeper, but without rope or climbing gear we couldn't descend safely. So bubbling with happiness to having found a new segment of passage, we made our The Alaskan Caver Volume 27 No. 3 p age 8

SUST AINABLE MAPPING.... continued fro m page 9 the cross-sections, but the interrelation of these forms are of importance and best presented in a longitudinal The first oppositional question to that might be section A good example is presented in Fig. 1. [EditorÂ’s why is it not sufficient to have a projected section note: Shown in the lower part of this figure is what [projected profile]. The answer is that a projected appears to be a sketch of a combined extended profile section hides some important information. Let us and projected profile. When creating a finished cave assume a S-N plane for projection, and a cave passage map I prefer to use projected profiles. I will add that falls first to the south (thus is represented "correctly" additional sections, projected from different angles in in the projection), before it turns west and continues order to portray passages that do not view well in the with the same dip. This portion will be represented main projected profile. This way it is easier to compare resembling a vertical shaft. If now there are important the plan view with the profile.] changes in cross-section of this passage, then this Cross-sections are very important too: They give cannot be seen: information is lost. A good mapper can the shape of the actual passage, which is also very construct a projection with the help of plan and informative in terms of determining speleogenesis. In order to portray the important geologic features of the cave, all three views (map, longitudinal section, cross section) are needed. WHY A WRITTEN DESCRIPTION? The answer is very simple: Did you ever try to draw a bat into your plan (to scale, of course)? Or the extent of possible flooding danger you observe on the cave walls? How do you represent your ideas about the cave's genesis? The written description is an invaluable source of information that may be very important, not only scientifically, but for basic cavers: Equipment lists, flooding danger, types of rocks encounter ed, unstable breakdown, gypsum occurrences, biology and genesis... all these things cannot be represented graphically and have to be written down. Thus, the description is not a marginal text describing only the things you can see on the map yourself ("T o the left, a passage leads to a shaft...") but all your important observations. And YES: Everyone can observe important things! Even you can do it! This is a very good question at first sight, because longitudinal section, but it is much more difficult (or in it is the precise drawing that takes most of the mapping case of changes in passage inclination, impossible) to extract a longitudinal section out of a projection. Projections are important for having the 3Drepresentation of the cave together with surface features. However such projections are usually done with a computer, since the mapping data ar e processed with it in the first stage. Longitudinal sections can give insight on fracture guidances and bedding planes which cannot be seen with a plan view alone. Longitudinal sections can give comprehensive views of expected difficulties (pits, crawlways, waterfalls etc.) and can thus be useful for planning a next trip. They represent the total development of the passage to scale. The foremost and most important use of the longitudinal section is that it gives information about the caves genesis! All the fractures a plan view may give, all the sediment displayed, cannot give half of the information a longitudinal section does. Is the passage of phreatic genesis (i.e. a rounded tube)? Or is it a vadose meander? Or a superposition of both, a keyhole passage? Sure, all this information is contained also in WHY PRECISEL Y DRAWN MAPS AND NOT ONL Y TOPOGRAPHIC DAT A OR SKETCHES? WHY A LONGITUDINAL SECTION, WHY CROSS SECTIONS? WHY PRECISEL Y DRAWN MAPS AND NOT ONL Y TOPOGRAPHIC DAT A OR SKETCHES?
