Greene, H. 198 8 May (cont.) creosote bush, and I could see through binoculars that it was eating a small object (piece of lizard?). Then Robert spotted an adult Gopherus agassizii resting on a lava spire ~50cm high, which I mooed and photographed. John found two Gopherus agassizii on the lava flow at an area of clay-like soil, where there were two fairly freshly dug areas. Were these places where the tortoises "mined" minerals ala R.W. Marlow? One was a large and one was a medium tortoise. I saw and missed 1 Gopherus and John cought a juvenile. We later (~7:30pm) stomach flushed both that we caught but recovered no food. Saw numerous Uta but caught none. Left ~1430 and ate at a restaurant in Indio, where there was a huge sign about what to do if someone clubbed on their food on the exit door, very visible as we were eating! Started east on Nate Trail Hwy. 3 mi W. Arroyo San Bernardino Co., California Stopped here and caught 5 Sauromalus at the N. edge of the Arroyo Crater lava flow, where it is closest to the hwy.
