Schist rock is found in several locations in Arizona, primarily within the Yavapai County metamorphic core complex, which is characterized by high-grade metamorphic rocks including schist. Here are some specific areas:

* Black Hills: This area in the Bradshaw Mountains is known for its schist outcrops.

* Mazatzal Mountains: Schist can be found in the Mazatzal Mountains, specifically along the Mazatzal Wilderness.

* Superstition Wilderness: While primarily known for its granite and volcanic rocks, schist can be found in the Superstition Wilderness as well.

* Santa Catalina Mountains: Though not as common as in other areas, schist can also be found in parts of the Santa Catalina Mountains near Tucson.

Note: It's essential to consult geological maps and resources specific to Arizona for accurate and detailed information about schist rock locations. The Arizona Geological Survey and the U.S. Geological Survey (USGS) can be great resources for this purpose.
