Quast 1948 Journal 64 May 15 4 miles N of La Paz, Sea Level, Baja California Minimum Temperature last night was 63°F, maximum today of 103°F. At 7:30 this afternoon almost had our two tents carried away by a small whirlwind. Looked for bats flying near camp from sunset to dark this evening, but saw none. May 16 Same location. Minimum temperature last night was 68°F. A strong steady wind started blowing from the south at sunset with clouds in the west, probably accounting for the higher temperatures. I have noticed that the nights seem to be coldest in this region when the air is still. 47 live traps set in same region as the night before last yielded 1♀ Peromyscus eremicus (#183) and 1♂ Procyonax spinetus (#184). The traps ran vertically up the rocky hill east of camp and the two mice were caught about half way up the slope. About four mice were caught by Dr. Benson, Murray, and Lewis together. 4 Sherman sets caught nothing. A Frigate Bird and an Osprey were seen at sunset yesterday. American Vultures are common here as elsewhere on the peninsulas. Left this location about 10:00 A.M. for points south of La Paz.
