The Poudre Canyon is a narrow verdant canyon, approximately 40 mi (64 km) long, on the upper Cache la Poudre River (called the "Poudre" for short, which locals pronounce as "Pooder") in Larimer County, Colorado in the United States. The canyon is a glacier-formed valley through the foothills of the Front Range of the Rocky Mountains northwest of Fort Collins.
The canyon begins in northern Rocky Mountain National Park, at an elevation of approximately 9,000 feet, where the Poudre descends from near the continental divide. It winds gently to the northeast, then east, descending the slope of the Colorado Tertiary Pediment, emerging through the southern end of the Laramie Foothills north of Bellvue at an elevation of approximately 5,000 feet. Except for the small upper portion of the canyon north of Rocky Mountain National Park, State Highway 14 runs through the canyon. The route of the highway provides the principal vehicle access to the canyon and furnishes a road link between F (from [www.wikipedia.org](http://www.wikipedia.org/wiki/Poudre_Canyon).
