4Spring in ChiapasPersons: Blake Harrison, Jill Dorman, Bill Steel, Cindy Coeburn, MikeBoon, Irv Grahm, Bob West, Gary Napper, and Charlie.This group left Austin April 5 and arrived at San Cristobal, Chiapas,on April 10. From San Cristobal they headed for the village of Chenalo buttook the wrong road in the dark so had to spend an extra night on the road.The next morning they finally arrived and talked to the priest who informedthe cavers that the village dumped its sewage into the river that flowsinto the cave. Despite this information the cavers decided to go ahead withexploration and went down to the cave to w~tch the sewage-foam flaked waterenter the 40 by 80 foot entrance. At the end of the dry season the streamwas very low, about 15 feet wide and 2 feet deep. They missed meetingNorm Pace and a car from Canada as the priest told them the others hadleft. Pete Thompson with Linda Thompson, Christopher Smart, and Ian Drummonddrove out to see the cave despite the tales of the priest and met the othergroup. After a reconnaisance on the first day, the combined group pushedthe Chenalo Sumadero to where it sumped in a debri filled lake about 3500feet into the cave and perhaps 200 feet below the entrance. They had expectedPeter Lord to join them, but later learned that while they were inChenalo Peter was having appendicitis in Oaxaca.After a day of R&R in San Cristobal the group drove out the new 16Kmroad over the mountain to Sumadero Yochab. This new road saved them afour hour walk and everyone arrived at the 60 X 80 foot entrance refreshedand ready. They had found Norm Pace in San Cristobal so the group now 13strong started rig~ing Sumadero Yochab. The first day 9 people moved 8duffel bags of equipment and rigged the first 2000 feet to the base camp450 feet below the entrance. To reach base camp 8 drops had to be riggedincluding a 60 foot drop into a large lake, and four short ladder drops.Rigging was difficult as ropes and ladders must be carefully arranged tokeep the climber away from the force of the falling water. The next fivedays were spent in exploration -- the push crew of Boon, Thompson, andSmart spent the entire five days underground, resupplied by two surfaceto camp trips. They were able to push the cave only 300 feet furtherhorizontally and 100 feet deeper as for almost the entire distance itwas necessary to place expansion bolts in order to avoid climbing inwaterfalls. The ri~ging was left in the cave after the push trip and thegroup returned to San Cristobal for a day of rest. At dark they drove backto deri~ the cave, but next morning Bill Steel and }1ike Boon decided tomake a final push and spent 21 hours in a last attempt, but they were onlyable to explore a short distance further. The mornin~ after Bill and Mikereturned, Norm Pace, Gary Napper, Blake Harrison, Bob West, Jill Dorman,and Irv Grahm spent 14 hours derigging and carrying out the six duffel bagsof equipment. There was a total of eight bags, but two had been removedby the push crew. However, the next day when they started packin~ theycould find only seven duffel bap,s -- one was missing. The bag containedmore equipment than the group could afford to lose -- so they agreed topay ten dollar~ per person for three volunteers to return into the caveand retrieve the duffel bag. Bill Steel, Gary Napper, and Jill Dorman
volunteered to rescue the bag. They did not know where the missing bag hadbeen left, so they had to carry enough equipment to reach the base camp. Afteran easy trip in, the bag was found at the 200 foot level and the three volunteersbegan the return trip. When they reached the large lake at the bottomof the 60 foot drop the water was muddy and extremely rough. Water had coveredthe log the belay line was tied to and was apparently rising rapidly. Billgrabbed Jill and told her to get out quick. She jumped into the swift waterwith her side pack still on her shoulder. The water was deeper than shethought, her light went out, and the pack slipped down over her arms andtangled in the belay line. She gave a cry, but managed to make it across thelake. Bill then came across and tried to rerig the belay line above the lakelevel and dropped the rope. Jill climbed up and went for help. She reachedthe entrance to find the surface crew had just weathered a severe storm.Hail stones still covered the mountain but the storm was over and the riverwas beginning to subside under clearing skies. Boon and Harrison gatheredtheir equipment and went in to assist with the last section. They met Billand Gary about 400 feet into the cave and stopped on a rock to discuss thesituation. As the surface crew was reassuring the recovery crew that theworst was over, the cold water closed over their rock. They were surprisedas there was no sign of further rain when they left the entrance a fewminutes before. But the water was undoubtedly rising rapidly. The caversand their three duffel bags were suddenly in a precarious position. The twominute walk to the entrance became an hour's effort against the current.Finally they could not pull the duffel bags against the force of the watereven with the rescue pUlley, so they tied the bags off and ran for theentrance. The stream had risen almost against the vertical wall, leavingonly a narrow path -- until they came to a boulder wedged against the wall.The swift current prevented passage on the stream side, but fortunately,the cavers were able to squeeze through a small hole between the boulderand the wall just before water washed through their escape hole. Upon reachingthe entrance they discovered the reason for the sudden rush of coldwater -- the hail left by storm had melted producing a flash flood. Thenext day they returned and retrieved the equipment. The volunteers hadearned their ten dollars -- though Jill agreed to take five dollars and asubscription to the Canadian Caver.P.s. OnJill Dorman as toldto Bill Russellthe first day of rest in San Cristobal they had received a post cardfrom Austin with the news that the landlord was going to evict cavers fromthe Kirkwood Caver House at the end of the month. So after Yochab they feltit was time to start back to Austin. Bill Stone and Irv Grahm stayed inChiapas to look for new caves with the aid of advance copies of the newChiapas topographic maps. The return trip took 49 hours from San Cristobalto Austin where they found the landlord had relented and they could stay.P.P.S. While Yochab was flooding Mark Shawcross and crew camped at theentrance to Sumadero Chicja were hit by the same storm. Water rose rapidlyinto the camp and all the equipment could not be gathered in time and asunto and altimeter were lost. The group also met Eian Finn and crew atRanco Nuevo where they found that camping was no longer permitted at thecave.5
