Quart 1948 Journal 59 May 11 Pozo Grande 25° ft 25°46' N 112°02' W Baja California Pozo-Grande is a grouping of about eight delapidated houses near the road crossing th Magdelena Plain. Immediately east of the houses and near the water hole 200 yards west of th houses are rocks and strata containing a very high concentration of shells and other fossils. A few willows grow around the pond and palms east of it near town. The sur- rounding flat countryside contains Opuntia, Mesquite, and Cardone, We were told that the water hole contains water all year around and that it is frequented by many bats in the evening - especially in the summertime. Caught one Toad (#170) last evening hopping in soft sand 25 feet above the pond. The pond contains one Eube and a few fish. Many ducks (Baldpalo?) frequent th pond at this time of year, about 50 attempting to land here at dusk. The road from Comondu to here is in very good condition compared to the road north of Comonda. Many sea turtles are caught by the residents in the ocean west of here. Minimum temperature last night (Pozo Grande) was 47° F. The night was quite damp and
