Quast 1948 Journal 86 May 26, El Carrigalito, 1400ft, 5mi N Santiago, Baja California Dr. Benson and I re-estimated the dimensions of Cave #1. It was decided that the cave consisted of two rooms and the entrance. The opening was approx. 13 feet in width and in height. The first room was about 30 feet high and ten feet high, with several concavities in the ceiling about 3' x 5' ending in flat horizontal ceiling. The opening between the first and second rooms was approx. 10' x 10'. The second room was about 20 feet high with an oval depression in the ceiling ending in flat, horizontal sandstone, this depression being about 8 x 15' in dimensions. This cave is about 70 feet long and illuminated clear to the end except for the small side branches containing the bats in depressions and on its flat walls. Upon entering the cave, the two groups of Myotis started "chittering", but very few flew despite our turning the light of our flashlight upon them. They were in two groups as mentioned before. It was about 10:30 A.M. when we visited that cave. Finally Dr. Benson took a long stick and actually had to push the Myotis velifer with it to make them fly. A furrow remained in the group where those touched by the stick had flown.
