San Luis Potosí Sótano de Huitzmolotitla El Sótano de Huitzmolotitla http://digital.lib.usf.edu/SFS0054910/00001?search=Huitzmolotitla Sierra Madre Oriental Xilitla highlands Aquismón Tlamaya No published map in AMCS. Partially mapped by Terry Plemons, Terry Raines, and T.R. Evans of the University of Texas Grotto of N.S.S. Leaving Austin on Saturday, 22 December 1962, they hiked the Xilitla area and found many caves and pits. On Saturday, 29 December 1962 they explored Sótano de Huitzmolotitla:
"They entered at 9:00 AM. Saturday and started the laborious task of mapping. At 9:00 AM they reached the point of the previous exploration they made and stopped mapping in order to explore.  At this point, 5,270 feet [1606 m] were mapped. The depth below the entrance level is 671 feet [205 m], making it the deepest surveyed cave in Mexico. They explored another 400 feet or so and encountered two waterfalls in rapid succession, both being about 12 feet [3.7 m] high. Below these , there was wall-to-wall water about 15 feet deep. Being unable to go farther , they checked the upper levels and were stopped there too. Inner tubes, air mattresses , or rafts will be necessary on the next trip. There are no signs of the cave's ending and the passage is so high that there is doubt that a siphon will be possible. After dining on Kipper Snacks and the like, the three started out of the cave around 12:00 AM and reached the bottom of the 161-foot [49 m] drop around 1:30 AM. By 3:00 AM they were at the bottom of the 344-foot [105 m] drop and because two of the three carbide lamps perished down the first drop, sacked out until 8:00 AM before tackling the 344-foot drop. (The entrance to this cave is made up of two long drops, the first of 344 feet [105 m], the second of 161 feet [49 m]—505 feet [154 m] to cave level!) By 9:30 AM they were all on the surface, rested awhile, then began the laborious task of hauling up the rope and packs that were attached to it. [Length: 5270' or 1606 m mapped + 400' explored = 5670' explored = 1728 m. Depth: 154 m + 3.7 + 3.7 = 161.4 m or 529'. AMCS database lists the cave at 3003 m long, 245 m deep, at elevation 520 m.]

CUEVA DE DIAMANTE, 4th deepest cave in Mexicoin 1978 at 621 meters.
AMCS surveying teams mapped this Sierra de El Abra cave to -120m in
December, 1974. In March 1975 the depth was extended to -300m where an impassable fissure was encountered. December 1976 saw a return trip to push a high level fissure, "The Canyonlands" with success (-466m). This group ran out of rope. In December 1977 the cave was bottomed at -621 meters. One higher level lead remains unchecked.
