Hanken, James 1975 Journal Mexico trip : Puerto de la Zora -> Valles 6 May 1100 hrs. The hot weather continues : tonight at the Hotel Valles in Cd. Valles the outdoor thermometer read 97 at 9:00 PM. After breaking camp this AM at our site outside of Puerto de la Zora we spent approx. 2 1/2 hrs. from approx 9:00-1130 hrs carrying the search for suitable caves and associated salamanders. Sam Sweet went down two more, one to a depth of ~100' and still had not reached water nor seen any sign of salamanders. Both caves seemed otherwise suitable for salamanders (Chiroptera- triton mosaueri) and it seems probable that they are now dormant even at the surface with respect to this habitat due to lack of moisture. While Sam ventured into the depths, those remaining above ground (Philip + Allen Green and myself) busied ourselves with turning cover objects and trying to capture some of the numerous Sceloporus seen about. The area is comprised of pine - oak forest with extensive limestone rock outcrops sometimes reaching over 20' in height. The Sceloporus were abundant on the rocks, basking in the bright sun, but were extremely wary
