Designed for the amateur naturalist, this guide describes 90 hikes chosen because they lead to some of Oregon's rocky wonders. Along with the geologic description, directions to the site, a description of the trail, and details such as the topographic and geologic maps for the area, level of difficulty, precautions, and other sensible information are provided for each hike. New to the second edition are appendices with hikes listed by rock age and a succinct guide to rock identification. B&w photos are included with each hike and for the identification guide.
