Greene, H. 1990 June 4 (continued) me (as evidenced by pupil movements), perched on a boulder w/ binoculars ~5m away. After ~5 min of immobility the head was lowered and the snake crawled slowly (several meters/min) w/ head periodically directed to the side or down at which time the tongue was protruded. Seemed to be prowling. From ~0900-1600 Claudia, Tuke and I drove north into southern Nye Co. and back to Granite Cove. We drove north on Kelbaker, turning NE on Eakin Mine Rd., which took us over a spectacular black lava field w/ several large red cinder cones. Besides many Callisaurus draconoides and Cnemidophorus digitus, we saw a black Gutaphytus tincntosre basking on a rock, which escaped; a large scarred Sanfelicia w/ red marks, also on a rock in full sun; and a Phrynosoma platyphrios - this on Lima Dome, ~0.3m above ground in sun on the rim of a fallen Joshua tree trunk (photos). Drove north on the road from Lima (we came out on it from a dirt 1-lane ranch road), across I-15 and north around the east edge and over the Kingston range, finally through [? Tecopa] and south on Hwy 127 to Baker and back to the Granitos.
