Mayhew 1959 Journal 20. Feb. 5 Mojave Desert, Colorado Desert, Riverside & San Bernardino Cts., Calif. except for a few spots a few hundred yards long each. We drove through the eastern edge of 29 Palms, then turned east on the road to Amboy. We drove until we reached the dirt road that goes to Dale Dry Lake. This is a good road that by-passes the chemical plant on the edge of the lake. This road intercepts another road that goes south of the dunes on Dale Dry Lake (this roads runs from Rice to 29 Palms). We found abundant tracks of Urea scoparia in these dunes, but saw no lizards because it was already duskdown. This should be a very good location for obtaining specimens of Urea scoparia. We left the area at 1730. This time we stayed on the road that goes from Rice to 29 Palms (called Dale Road at this point), and started west toward 29 Palms. The collecting site we plan to use is 18 miles east of our prospective camp- site, and 3.4 miles east of the end of the pavement (our campsite is 1.6 miles east of pavement end). (I failed to mention that several annuals had sprouted in the dunes at Dale, and moisture was found in the soil at a depth of about 4 inches.) Dale Road
