Murray 1948 132 Journal June 26 Cerrogo San Suis, 300+ ft., 9 mi W Calmelli, Baja Calif. hole, supported by beams, which probably connected with the shaft below. Dr. Benson went part way down into this and scared up 1 Myotis californicus and a barn owl. Waited at dusk in the wash for bats but saw none. There were nighthawks and I heard a poorwill. We spent the night where we were, next to the wash. June 27 10 mi SE Mesquital, 400+ ft., Baja Calif. We drove onward again today, but not very far, for our luck ran out and a wheel came off of the Dodge. This calls for a new wheel, so Dr. Benson and Quast set out for Santa Rosalia to have one flown down, while Tevis and I prepared for a long session in the middle of nowhere. We rebuilt the road around the truck, and made camp on the other side. Since we are going to be here several days, we will try to get as complete a picture as possible of the life on the Vizcaino Desert. This seems to be as typical a part as any. The soil here is hard packed and sandy, with the surface more of a gravel. Color is light with a yellowish-tan cast. It is unwooded except for full sized washes, and very flat.
