W. Riever 1956 Journal 5 Mar. Texas: Culberson Co., Guadalupe Mts, McIltrich Canyon Two Sceloporus undulatus taken in late afternoon, one in camp the other on limestone cliff adjacent to camp. One Sceloporus poinsettii (?) taken in late afternoon by peeling off loose flakes of rocks from a south-facing cliff near camp. The particular flake was close to the ground. Much more rock peeled off with no results, probably because south-facing rocks get too hot from sun in summer. Most rocks dry underneath but some with dampish soil substrate. One lizard, probably a skink, seen in vicinity of rocks in shaded area of small oaks. Dense mat of dead leaves on ground. Other animals noted: tracks of deer and elk, scats, of fox (?) 6 Mar. Yesterday evening a strong wind came up blowing down canyon. This morning wind of gale proportions and so camp broken without further collecting. Mr. Pratt, when we returned the key to his wildlife refuge area, informed us that in 1924 the elk were introduced into the canyon, a total of 50 animals. He estimates currently 15 remain the others having gradually starved. He also estimates 35 deer present, soap mountain sheep present on ridges. As seen from distance there must be fairly large stands of yellow pine on higher levels of ridges. Returned to El Paso in morning.
