Munday 1948 Journal July 14 8 mi N Rosario, Baja Calif. On the west, with a deep cut wash on the other side and a tall cliff beyond it. The whole countryside is mountainous and rugged. Set out 105 live traps, 30 up on the nearby hillside, a hard crusty surface of soil with a little sandstone. The vegetation is almost entirely bushes, fairly dense, and a few buckeye trees or bushes. 20 more were on a flat place by camp, featuring only very low scattered bushes. The other 50 went along the far bank of the wash, which was silty and thickly grown with bushes and large agaves. Cactus is greatly lacking throughout the area, with only an occasional cholla or pitahaya. Found a Crotalus ruber just the other side of a brush from camp, running out in the open. Did not move while I went back for a gun, returned, or even when I shot it until a few minutes later. July 15 Same location On the hill caught 10 Dipodomys , 7 D, 19 Peromyscus eremicus. In the wash was 10 Perognathus
