Rocks Above the Clouds

Book excerpt: Rocks Above the Clouds is the first geology book written for climbers, scramblers and hikers. Along with six maps and a range-by-range geologic description of what to expect in the Colorado mountains, it includes some very curious information on the Colorado Fourteeners.Rocks Above the Clouds explores how the nature of mountains and the challenges they present to the climber and hiker are influenced by the rocks that form them--in other words, by their geology. After describing the types of rocks found in mountains, the authors cover the geologic process from the big bang to the present.
