Mayhew 1959 Journal 21. Feb. 5 Mojave Desert, San Bernardino Co., Calif. becomes Baseline highway where Gold Crown Road intercepts it (6.9 miles west of pavement end). This is a road that enters Joshua Tree through Pinto Basin. Baseline highway is called 29 Palms Highway where it is intersected by Utah Trail (the paved road through Joshua Tree). The collecting site is 25 miles east of this intersection. There are 21 1/2 miles of pavement between this intersection and the collecting site, which may be rather good for night collecting. We reached 29 Palms at 1815 and UCR at 2005, after driving 306 miles today. Thus, we drove 877 miles on this trip, and 1,552 miles on the 2 trips between semesters. Including the collecting trip during finals, 2,034 miles were travelled during this 2 week period. Feb. 18 Santa Rosa Mts., Riverside Co., Calif.
