Mayhew 1959 Journal 89. Aug. 26 Wrightwood area, Los Angeles Co., Calif. We reached Wrightwood at 1500, and found some Sceloporus occidentalis a few moments later. We drove west on state highway 2 to Big Pines Recreation area, then turned left and drove up to Blue Ridge. We caught both Sceloporus occidentalis and Sceloporus gracilisus there. We stayed in the area (8300 ft.) until sundown to see how late any of the lizards stayed out. Only Sceloporus gracilous were seen at this elevation (the last Sceloporus occidentalis we saw was at 7700 ft.). The last lizard was seen at 1825. Sunset at that location occurred at 1827. The air temp (30°) at this time was 13.0°C. We caught 43 lizards today, as follows: Sceloporus occidentalis - 27 (17 ad ♂; 8 ad ♀; 1 im ♂; 1 im ♀) Sceloporus magister - 3 (1 im ♂; 2 im ♀) Sceloporus gracilous - 10 (7 ad ♂; 3 ad ♀) Uta stansburiana - 3 (2 ad ♂; 1 ad ♀) Thus, we caught 65 animals during our trip, as follows: (Max. temp. today - 90° F.)
