R.K.Selander, 1953 Tijuana to Alaska, Baja California, Mexico Feb. 7 low desert scrub. About 3 miles west of Alaska, on the summit of the mountain there is a fair belt of pinon-juniper forest running north-south across the highway. The country is hilly and rocky - great boulders with the trees scattered in between. Pines seem to be dominant. Yuccas are also present among the pines as is a small agave. At Alaska, + 3100 ft., I stopped for the night. As I got out of the car three scrub jays flew into a pine near by and I collected one. Many goldfinches (green-locked?) heard and seen. Feb. 8 Wind blowing strongly this morning. At 8:30 I continued east. About 2 miles east of Alaska (on the down grade) the land becomes even more rocky so that in many places there is no vegetation. Some slopes here along a small agave growing on them. The pinon-juniper belt is perhaps three or four miles in width. East of the Sierra de Trancs the land is flat and barren - real desert with only sparse low desert scrub vegetation. The north end of the Sierra de los Cucopahs is rocky and almost devoid of vegetation. Approaching Mexicali the land is farmed as it is from Mexicali east to San Luis.
