Roadside Geology of UtahIf the states had been published in order of geological interest Utah would have been first. Halka (Pages of stone) writes gracefully and competently of the state--most of the interest lies in the eastern and southern wedge. The land forms here are extraordinarily dramatic and are visible in intimate detail owing to the lack of forest cover. The series neglects a good index map. No bibliography.
