Mount Zirkel Wilderness
The Mount Zirkel Wilderness lies within the Routt National Forest in northwestern Colorado. It was one of the original areas protected under the 1964 Wilderness Act and has since been expanded twice to its present size of 160,648 acres. The Wilderness straddles the Continental Divide in the Park Range and the Sierra Madre and offers a diversity of ecosystems from sagebrush meadows in the lower areas, through pine and spruce/fir forests and on up to alpine tundra. It contains the rugged peaks of the Sawtooth Range and the headwaters of the Elk, Encampment and North Platte rivers.
