Murray 1948 34 Journal Apr 24 12 1/2 mis by road El Marmol, 2200 ft. Baja California That the sheep were still plentiful. We went on, climbing a little, passing a number of low table mountains. The soil became granitic and there were many large granite boulders. 12 1/2 miles up the road we camped beside a great rock. Noticed that these are exfoliating in large thin sheets yet are not much decomposed. This is a flat stretch, very rocky, with many cirus, a few cardons, cholla, viznaga, pitaya, creosote and several kinds of low gray shrubs. Set out 50 live traps about 50 feet apart largely among rocks. Placed 9 Schuyler traps in front of wood rat nests. These were quite common, always among large masses of boulders or a very large single one. Their nests were mostly dried parts of cholla where exposed, but running in under the rocks. Shot a Uta stansburiana in the sand. Apr 25 Same location. The traps had 10 Perognathus fallax and 1 # Peromyscus eremicus. There was a full moon in a clear sky last night. Left about 1 P.M. Found the terrain becoming much rockier with great granite outcroppings. There were more cardons
