The Granite Dells is located outside the city of Prescott in the US state of Arizona. The Granite Dells are a exclusive geological formation comprising of colossal granite boulders that have eroded into rounded bumpy and strange shapes giving the rocks a rippled appearance. It is believed that these exclusives rocks formed 1.4 billion years ago at a depth of 2-3 km, before they were exposed by weathering. This process is known as spheroidal weathering, common in granitic terrains, the rocks assumed rounded shapes and other rare rock formations that characterize the Granite Dells.
Thus, two very picturesque artificial reservoirs “Watson Lake and Willow Lake” situated nearby the formation. The two lakes combined with abundant hiking trails offer a great place for boating, picnicking, hiking, and birding. The Granite Dells rugged beauty and dramatic rock shapes is the perfect backdrop of surrounding mountains, with acres of open space, and planned hiking trails with connection to more than 400 miles of public trails. The Dells' granite has strangely high uranium content, and thus homes built over the granite should be checked for radon leaking from the granite.
