Geologic Maps With Metamorphic Rocks & Geologic Structures
Metamorphic rocks are locally exposed across Arizona, from the bottom of the Grand Canyon to some of the mountain ranges in southern Arizona. The largest exposures of metamorphic rocks are in the rugged mountains of central Arizona. Geologic structures of various types and sizes are also exposed across Arizona and thoughout much of the Rocky Mountains regio

Geologic Map of the Brady Butte Area
The Brady Butte area is a rugged wilderness area in the Bradshaw Mountains of central Arizona. Access to the Paleoproterozoic geology of this area is limited, except for the highly washboarded road leading to Crown King and the Senator Highway in the southernmost part of the map area. The Proterozoic rocks of the Bradshaw Mountain host abundant ore deposits that were prospected and mined in in the late 1800's and early 1900's.
