On September 3, 1964 President Lyndon B. Johnson signed into law the Wilderness Act. This historic bill established the National Wilderness Preservation System (NWPS). In Colorado, 3.6 million acres have been protected as wilderness in the last 50 years. Each area has a story – a story of citizens working together to permanently protect some of the most iconic places in our state. Today, Coloradans are working to add deserving places like Hermosa Creek, parts of the San Juan Mountains, and Browns Canyon to the National Wilderness Preservation System. Look at a current Map of Colorado Wilderness Areas.
