🇲🇽 Cenote Dos Pisos

Traced from the cave-ha.com Dos Pisos cave lines map (Alex Vronsky 2024 lines over the Nadia Bernie 2010 survey); the scale comes from the 150 ft scale bar on the Bernie survey sheet in the owner's vault and passage names from that sheet. The line starts out of the water and runs through about 60 m of small, silty passage; the main route runs NW to Cenote Dos Pisos Norte (about 1 km), the western lines continue toward the Monkey Dust section. Depths and penetration marks on the survey are unreadable at the scan's resolution and are left out, except that the survey marks about 3,480 ft (≈1,060 m) of penetration at Dos Pisos Norte (system average about 6 m, maximum 24.4 m). Positions are approximate.
