where Prescott
the hike     The Granite Dells is a geological feature north of Prescott, Arizona. The Dells consist of exposed bedrock and large boulders of granite that have eroded into an unusual lumpy, rippled appearance. Willow Lake is a small man-made reservoir in this formation; this, combined with numerous hiking & biking trails and rock climbing routes, makes it a popular outdoor recreation area in the region. Geologically speaking: the Precambrian Dells’ granite has been dated at 1.4 billion years old. Its plutonic rock was intruded at a depth of around one or two miles. These cover rocks have since been eroded away. Weathering along joints produced the rounded boulders and other unusual rock formations that characterize the Granite Dells. This process is called spheroidal weathering, and is common in granitic terrains.
    Hiking in Prescott’s Granite Dell is like getting lost in a stone age labyrinth. The network of paths on the north shore of Willow Lake coil through hulking quartz-studded granite buttes squeezing in and out on the paths in heaving accordion style. The rugged meandering loop trails move seamlessly from claustrophobically tight spaces to airy exposed promontories with unobstructed vista. On these rocks the trail follows spray-painted white dots that serve as directional beacons.
