Composed of everything from volcanic island arcs and deep ocean sediments, to parts of old continents and even pieces of the deep subcrustal mantle of the earth, Washington's North Cascade region is a true geologic mosaic. Here, authors Tabor and Haugerud reveal that the spectacular scenery of these mountains is matched by equally spectacular geology.
Beginning with a summary of the geologic history of the North Cascades, the first section also offers the novice a primer on geologic terms and processes. The second section covers 150 points of geologic interest organized by the major rivers of the range and arranged along roads and trails. Many details of the rocks and geologic processes in the North Cascades are introduced, making this a must-read for those studying the region.
