This district is located in the northern foothills of the Bradshaw Mountains, between Prescott and the Agua Fria River.
Prescott lies in the basin of Granite Creek, in the area of massive Bradshaw granite that occupies the SW corner of the Jerome quadrangle. The granite is adjoined on the east by the north end of a great mass of Yavapai Schist, which is tremendously injected by granite and pegmatite. Much of the granite rock exhibits a crude schistosity. At the western contact of the schists the rock seems to be mainly a dense amphibolite. At the bridge across Lynx Creek the exposures show fissile schist with cherty beds injected by granite. In the granite are veins of quartz which are themselves cut by veinlets of epidote.
East of the schist the Bradshaw Granite reappears, forming a belt about 2 miles wide, which is in turn adjoined by schist extending to the Agua Fria River. Tertiary volcanic tuffs cover a few areas on the hills near Prescott.
