Journal Maybeo 1959 14. Feb. 2 Colorado Desert, Riverside & Imperial Cos., Calif. proceeded S.W. toward a power line. The road along the powerline goes right past Lone Bunchan in Tule Arroyo. This walking dune is 4 miles from highway 99 by the route just described. The wind was blowing fairly hard while we were there, making the sand cut like a knife when it hit you. The area on all sides of this dune are very arid. Some beetles (6) were dug out of the sand of the dune. These were placed in bottle H to take back to Riverside to see if Luma motata will eat them. We feel luma must eat them to be able to survive in this very desolate location, and we know from other investigators that luma are present on this dune. We left the dune area at sundown and drove south to go around the southern end of the Salton Sea. I wanted to locate the swamp Engine Cardiff told me was east of Hland. However, we were unable to find it in the dark, so we drove north on highway 111 to Mecca. Then we turned east on highway 195 and camped just east of the canal before the road enters Box Canyon. We reached this spot at 2130, after driving 266 miles today. The minimum temp. tonight is 43° F. (Beetles are Eusettus productus-see journal to 5/26/59.) page 59.
