Queretaro,located twenty-two kilometers north of the Xilitla-Jalpan highway. For 25pesos per burro, per burro driver, per day, we rented three burros, a mule,and a local farmer to transport 1300 meters of rope and food for twenty-threepeople to the village called Rancho Carrizal. two days north-east of Tancoyol.On the third day the motly crew set up camp in an area called Ojo de Agua.three minutes walk from the closed valley which contained EI Sotano de Socavon.The next day almost everyone entered the pit at intervals to survey. photograph,and make a biological collection in the large room at the bottom ofthe entrance drop.The entrance to Socavon is inthe end of a quarter-kilometer-longdolina. The top of the entrance isfifty by one hundred meters. withthe high side being slightly undercutfor a free rappel down eightymeters until you reach the neck ofa funnel. Here it ±s only ten metersin diameter. The low sideslopes to the neck and is coveredin ferns, lichens, shrubs, and largeEI Socovonleafed plants. After twenty metersthrough the neck. one finishes therappel, bouncing off a flows tonecovered wall in the side of an enormousroom, for a 180 meter drop tothe apex of a talus slope. Thisboulder pile slides away from thewall of the chamber for seventy moremeters to the damp dirt floor, 200meters below the entrance.The chamber itself is two hundredmeters long, one hundred meterswide, and seventy-five meters high.There are several huge formationsnear the wall opposite the entrancedrop, and a couple of pancake-sizedfried eggs in the northeast end.water has stood as much as one meterdeep over some parts of the flat siltfloor, indicating that there is norapid run-off once the rain trickles in. ~o side passages existmense room unless they are hidden below the silt floor, in which560 ft.60 ft.~in this imcasetheythe room aswould be full of silt anyway. A small population of parrots usehome.In the next few days, seven other caves and sotanos were found and sketchedor mapped. Xost were only thirty to seventy meters deep in two or three shortdrops close togetaer, ending in dirt plugs. However, a 200+ meter system withseveral drops was found close by; but it also stopped at about the same elevationas Sotano de Socavon, ending in a dirt plug.continued
3So the large-entranced sotano which AMCS cavers had been hearing aboutsince 1967 and which Bill Stone and Steve Ward had partially entered in Augustof 1974 was finally mapped. It did not turn out to be the recordbreakingdeep system we were prepared for. But Victor Benalcazar and MikeSchulte walked in from Azuismon, via Rancho Parada where they had been checkingtrails and rumors of more caves. There are still caves in the Xilitlaplateau to be found. May~e the next one will go.Don BroussardLOS SABINOS, S.L.P.: DEC. 24, 1974, Steve Barbee, Steve Beckman, Ken Dewire,Steve Joffe, Mark Minton, Paulette Minton, and Richard Minton.The above people had just arrived in Los Sabinos campground and awaitedthe co~ng of Harold Go]dstein, Karen Jacobson, Joe Maskasky, Tom Ramsey.This group arrived in Los Sabinos with several objectives--among them to filma Golondrinas trip and map Cueva del Aire and Cueva del Brujo.

They connected Aireand Brujo last year but exploration is not complete. Mapping these caves isdifficult not only because of complex steeply sloping rooms, but also becausethe cave is used as a shrine by the Huastecan Indians. On their lasttrip the group was invited to help worship the Huastecan gods. The Indianshad killed a small animal and laid it as an offering in the center of a clothwith broken cave formations on the corners. The Indians taught the caversthe proper chants as they walked around the altar. Each time they wentaround they would take a drink of cana--the local whiskey--and sprinkle someon the altar. The Indians then pointed out their other offerings of smallcoins and various objects wrapped in leaves. After the services the Indiansand cavers left the cave in a spirit of fraternal goodwill.Despite their previous plans, when the group heard of the new road inthe EI Abra they decided to go there. First they checked Sotano de Locut,a one hundred foot pit by the road. Then they explored Sotano de Otates,checked north of the road and south along the face of the range. Several ofthe group pushed Cueva de Diamante to about the four hundred foot level; thecave still goes. Otthers filmed the trail chopping, did Sendero (the new 712'pit by the trail), took movies in Sotano de 1a Cuesta at the end of a threehundred foot rope, and then checked Sotano del Arbo1 since they had broughttheir rope. This pit had a 177' entrance drop to a room with a four secondpit on one end. The group then returned to Los Sabinos, happy but tired, tosee how much of their original schedule they could salvage.Bill RussellOverheard while trailbuilding in the El Abra:day until Christmas.""only one more chopping
