Rivita, dear 2012 Journal Oct. 11 Cueva Castillo, Mpio. Hualyos, Tamaulipas, Mexico (cont) ... for perhaps 70-80m. lots of cool cave formations, pockets, some stats. Maria found a big Christobitron on the cave wall. Kind of reminds me of C. madawini; big feet, slender, really long tail. Could perhaps be the species we got in caves in El Cobre, or C. multifidus. I found an Eleutherodactylus that escaped. Driving up today, we stopped and searched in a series of small mines and found 2-20 (or more) Eleutherodactylus on the walls; they seem abundant in the area. After Cueva del Brujer, we went to another large cave that was darker and darker (when I entered by day). I found another Christobitron on the ceiling of a small side chamber. I went in one more small cave with a really tight entrance and tons of stalactites but found nothing more. All together, we searched from 21:45-23:45, at which point we walked back to camp. It had been cloudy most of the day and warm, with a brief, light rain around 16:00, but cleared up by night and was a bit cool, perhaps around 20°C. A spectacular view of the stars. Wish we could stay here longer. Obviously many more caves to explore, and the road continues to Yerba Brava and Los San Pedros, both of which have caves, and also continues over the crest of the Sierra to Nuevo Leon.
