Granite Dells, Ancient granite formation in Prescott, United States.
Granite Dells is a granite formation north of Prescott featuring exposed bedrock and large boulders shaped by erosion into rounded, rippled forms. Watson Lake and Willow Lake sit within these rocky landscapes and serve as central hubs for hiking, kayaking, rock climbing, and wildlife watching.
The granite here formed around 1.4 billion years ago in the Proterozoic era as rock buried deep beneath the earth's surface. Over countless millennia, erosion and weathering exposed this ancient stone, revealing the region's complex geological story.
The Peavine National Recreation Trail runs through these granite formations along the former Santa Fe, Prescott and Phoenix Railway route. Hikers can follow this path today and experience how the landscape once connected communities by rail.
The formations are accessible year-round, with spring and fall offering the most comfortable conditions for outdoor activities. Both lakes provide starting points for different skill levels, from casual walks to challenging rock climbing routes.
The granite here contains higher levels of uranium, requiring local homes to be tested for radon gas. This geological feature makes the area an important location for studying natural radioactivity in rock formations.
