The Wilderness Concept and the Three Sisters Wilderness is a guide to understanding the Three Sisters Wilderness as wilderness -- its natural and cultural history as well as the philosophical, legal, and management concepts that keep it a wilderness.

The magnificent Three Sisters Wilderness, straddling the Cascade mountain range, beckons adventurers from around the world. One of the original fifty-four of the more than eight hundred such areas designated by Congress, it is Oregon's second-largest most visited and accessible wilderness. Championed by citizens of Bend, Eugene and beyond, its preservation under the Wilderness Act of 1964 was a community-wide effort to keep the dramatic vistas and diverse ecosystems available for all to enjoy. Join author Les Joslin as he explores the origins of the wilderness concept, the natural and cultural history of the Three Sisters country and the stewardship that preserves what is termed an enduring resource of wilderness.

A compilation of the geologic names of the United States, its possessions, the Trust Territory of the Pacific Islands, and the Panama Canal Zone.
