The Peavine National Recreation Trail follows the former railbed of the Santa Fe, Prescott and Phoenix Railway through the Granite Dells. This winding portion of the railroad connects to the Iron King Trail, which follows the route of the old Prescott & Eastern Railroad through the eastern Granite Dells. Both are rail trail conversions.
The Granite Dells is an area of bedrock and large boulders of granite that have eroded from a body of intrusive igneous rock (called a plutonic rock) that crystallized from magma that slowly cooled below the surface of the earth. Weathering along the joints produced the rounded boulders and delicately balanced and fanciful shapes that characterize the geological formation. Ruins and artifacts also indicate that the Dells were once the home of Native Americans. The Dells have been dated as 1.4 billion years old. Hiking through the Dells evokes a visible and truly spiritual connection with the ancient. 1, 2
