Geologic Materials: 
alluvium, colluvium, and residuum associated with Lower Davidson Canyon facies, mixed conglomerate, reddish (Tpi); Turkey Track Andesite (Tpv); old alluvium (QTs); early Pleistocene river terrace deposits (Qor); and Miocene to Quaternary conglomerate with colluvial veneer (QTsc) which comprise 22%, 20%, 17%, 14%and 10% of the ELT, respectively
