4large depression. Only in the last 100 yards did we realize that itwas a great alpine meadow, perhaps a half mile across. This, we discovered,was Llano de Los Chiquitos when a lone horseman.. greeted usthe next day at dawn as we huddled around our campfire. Cold? - therewas frost on the llano till 9:00 AM: Upon explaininR that we were insearch of a great hole near 1a Silleta he professed lack of knowledgeof its location -- but invited uS to look into another hole on the llano.Our trail weary minds could conjure up nothing but amazement as we strolleddown the 100' wide 50' high passage of Cueva del Llano de los Chiquitos.Yes, there are caves above Xilitla:: Two thousand feet later we encountereda series of drops. Having no rope we exited and packed off to theeast. Twelve thousand five hundred foot Cerro de la Luz towered aboveas we labored up the alpine pass. By noon we crested out at around 10,000feet elevation. Llano de Caballo was-visible below. From there we descendedstill again into Llano de Conejo. A farmer there showed us a view ofla Silleta. From the bearing and estimated distance I calculated thatwe were within two miles of the hole. To our incredible amazement thefarmer said he knew where it was::After a restless night in our hammocks we were awakened at 7:00 AMby the farmer who was ready to hit the trail. We were half asleep forthe first 30 seconds, at which point we were rapidly roused into realityby his super sonic trail speed. Within 25 minutes we had ascended 1000'+to Llano de Caballo -- (it took 4S minutes to hike down the day before).The pace continued to a large white cliff which I recognized from theair photos a8 just above the hole. We could have started a fire withthe psyche sparks which were flying off: Fifteen minutes of trail choppinglater we were standing on the edge of Hoya de la Luz. With theexception of £1 Sotano I have not seen a more awsome entrance. Rocktimes averaged 7-1/2 seconds free. What frustration to have all 3000'of our rope back in the truck:We packed out that afternoon to El Barrio on the Xilitla-Jalpanhighway and camped at the Rio Santa Maria.The next afternoon was spent in Jalpan savoring Peso snow cones tillwe noticed this guy breaking into the truck. Much to our surprise it wasTracy who had just arrived by bus for the Nogal push. That night we droveto the end of the La Purisima road and packed up for a ten day, 500 meteror perish trip to San J08e. Fully anticipating the hardships of goingdeep with only a four man crew we spared no food -- two duffels worthof culinary delights. Two more duffels totalling 2000' of rope completedour burro train which left at dawn the next day. After setting up campjust above the Nogal sink, Tracy, Larry and I descended the Itsecond" entranceto Nogal. Surprizingly it ended in a methane lake 140' down. Bow did weknow it was methane? Tracy says, "We used to do this in Arroyo", and stirsu~ an immense cloud of gas. Since he was swimming with his lamp on we weretreated to a fine 4 foot high fire display with. Tracy jumping about in themiddle:That afternoon we sorted ropes for the known drops in Nogal, as thathad saved considerable time in Conchas.By dawn Larry was suffering from a bad case of the'Zumas and decidedto remain in camp. We quickly rigged to the first lunch room, termino ofprevious exploration, about -800'. Ninety feet below we pendulumed acrossa deep lake and continued down a flowstone cascade. This was followedshortly by a large drop. Gary descended on a 300' line. This pitch,
