L'DICKER 1958 (April 2 cont.) continues up. About 6.5 mi. E of Jacumba (yrd) the road comes into a valley which could have dips in it - this is the first seemingly suitable habitat since the small area at Mt. Spy. There is Larrea, yucca, etc. About 5.3 mi from Jacumba junipers come in pretty thickly but soil fairly sandy. This valley seems to extend southward a no. of miles + seems to be eventually enclosed by into. At ~ 4.9 mi from Jacumba the rd. descends to 3000 ft. At 2 mi from Jacumba the valley seems to extend southward 5+ miles + no apparent gaps can be seen. We continued through Jacumba to Boulevard to see the area + then turned around to set traps. The road begins to ascend gradually W of Jacumba. It began to rain as we came into 2-leaf Sage + continuing intermittently 3/10 mi from Boulevard we saw a Calif Jay.
