One color sheet, 30.5" x 46". Scale 1:100,000. From text: The northwest Cascades in Washington are underlain by rocks common to convergent plate margins of the world—notably blueschist, alpine peridotite, volcanic arc and oceanic lithologies, and tectonic melange. In this region, great topographic relief combined with extensive outcrop and excellent alpine exposures allow geologic studies pertinent to solving general questions of the origins of these rocks and the mechanisms of orogeny by which they are emplaced. The present map and largely descriptive report provide a data base for addressing these problems.
