July 14 Cerro Baul, Chiapas Mexico Spent all of the 12th writing in Tapachula for car to be fixed; was finally ready at 13:00 on the 13th. Drive to Acancayagua and searched for habitat at Finca da Esperanza, now called XX de Septiembre, 5 Km E of Acancayagua.

The cave is relatively small/narrow (only 1 person can advance in any given direction) but appeared to have quite an extensive system of passages. The rock surface was very moist with tons of [illegible] lots of caverock formations.

Stayed in the cave for ~30 min, but active search time was more like 10 min. The recent heavy rain appears to have caused the salamanders to be
