Quas 1948 Journal 122 June 16 La Paz, Baja California night the road north of Mulege was washed out the day before yesterday by a rain storm. June 17 Wend Llano de Nirey, 50+ ft. Baja California Arrived here about 6 P.M. yesterday after driving from La Paz. Minimum temperature last night was 53° F. No bats seen last night at dusk. We are camped on the border of a large circular lake bed that evidently contains water only after heavy rains. A large connected series of these beds occurs in this area, the road passing through many of them. This location has a bed about 1/2 mile in diameter, appearing absolutely flat in its center and surrounded on all sides except the eastern with low sand dunes sparsely covered with Opuntia cholla, Cardone, Ocotillo, and a few desert shrubs. On back of th. dunes more dense desert vegetation occurs. The playa is made up of dark silt and profusely covered with large mud cracks up to 10 inches deep. Growing in this soil are short bushes and plants of from 3 to 12 inches in height quite densely in most of its area. All these have been trampled by cattle and are dry at this time of year. Surrounding the playa is an intermediate area, between th. sand dunes and th. dry mud, covered with sand but having isolated hilltops.
