Greene, H. 1979 28 Feb Left Oakland Airport at 7AM w/ Dave Wake, Kaz Yanov, John Cadle for Ontario-Riverside. Arrived there ~8, rented 4-wheel drive van at JC Riverside, ate breakfast & drove up to San Dimas Canyon. San Dimas Canyon, 1.1 mi NNE Foothill Freeway, San Bernardino Co., California Sunny, warm. Steep, chaparral-covered slopes; canyon bottoms sparsely to heavily wooded. Water in streams. 1 Anceides lugubris, 1 Batrachoseps nigivertex, 1 Gopherus multicarinatus, 1 Thamnophis couchi. I saw 1 large Gopherus active in thick brush high on a hill, but it easily slipped away. Caught 1 w/ complete tail (tip later broken in sack) in lush grass in open, near trees at roadside. Heard it, then saw it moving towards a large sheet of cardboard. Seemed to fold legs and be moving largely by lateral undulation. (see general notes on this trip at end of 4 March)
