Residual Soil: clay, brown, sandy near contact.

GRANITE, gray slightly mottled with light gray, fine to coarse grained, (granite to biotite-hornblende granodiorite) moderately fractured, moderately to intensely weathered in upper portion and in near surface fractures, with a few stoped fragments of gabbro and quartz veins. Changes in grain size common highly variable and abrupt.
