Prescott is the epicenter of some of the finest bouldering to be had in Arizona. Small areas surround the city and because of elevation differences chances are you can find a place with good weather despite bad weather in the area. Wether its granite slopers, basalt pockets, or quartzite crimps, chances are you will find whole areas that will leave you satisfied... For a while.
Bill Cramer I believe will be putting out a new bouldering guide as of 2007 sometime. I am adding this spot for highlights, recomended lines, pics and what not.
