Palmer 1934 Itinerary \rm{mi. NW Warren Hill, Morongo Valley San Bernardino} Co., Calif. Dec. 28 cont'd. Then returned to The Windmill and drove on the Victorville road to Old Woman Springs, and camped \underline{about 7 P.M.} \rm{1 mi. W of} Old Woman Springs at Cottonwood Springs. The elevation there was about 3190 ft., as the benchmark at Old Woman Springs indicates 3186 ft. Cottonwood Springs is situated where a low "mesa" of volcanic tuff meets the main valley floor. This slight elevation extends back fairly level for about \frac{1}{2} mi. to some granite hills which rise rather abruptly S of Cottonwood Springs. It is covered deeply over much of its extent by fine dune sand. Most of this area has scattered shrubs of Creosote Bush A, Atriplex, Chenopodium, and other xerophilous shrubs. The hill H in the diagram is covered with dark volcanic "cinders" while hill B is entirely of granite Cottonwood Spring Mesa Valley Floor
