Quest 1948 Journal 77 May 23 Buena Vista 25+ ft, 23°35'N, 109°41'W, Baja California from the beach and next to a group of houses occupied by fishermen. We have been obtaining most of our meals at the house. 50 yards inland of us a sedimentary outcrop is visible and then the mesquite stop and the cactus and short bushes take over. The sedimentary outcrop is cut by an arroyo N.W. of camp which extends several miles west to the range of mountains called "Sierra Pinta". The mountains are covered with Fruta, Creosote, Ironwood, Ocotillo, Cholla, and Pitahayo dulces to a moderate degree, my being unable to call the vegetation either sparse or heavy. Large alluvial fans extend down from the mountains and water holes occur this time of year only at the heads of the arroyos and washes. Subsurface water is quite available in this region numerous wells occurring with windmills for pumping the water into tanks. From the hills as one looks down upon this area, one is impressed by the change in color between those areas supplied by subsurface water and those not. Almost every wash is very green in comparison to the alluvial fans, hills and mountains, the color being furnished by the green mesquite and Palo Verde.
