Mayhew 1960 Journal 5. Feb. 15 Dale Dry Lake area, San Bernardino Co., Calif. This morning at 0855 Frank Aubrey & I left UCR. We reached our collecting site at 1100The last house on 29 Palms Highway is only 3.4 miles west of our site (corner of Iron Age Mine Road & 29 Palms Highway). No reptile tracks could be found, but there were numerous mammal tracks visible. There was evidence of a very strong wind (or winds) having blown since our last trip. We could find no trace of reptiles anywhere, so we gathered our soil samples & ate lunch. Although it was a beautifully clear, calm day, the temperature was rather low: time-11/0: air temp.(30") - 14.2°C. .. .. (1cm) - 14.5°C. soil surface temp.- 28.2°C.
