Boulder Canyon

The Boulder Ranger District of the Arapaho and Roosevelt National Forests implemented its annual area closures at Blob Rock, East Blob Rock, and Bitty Buttress in Boulder Canyon on February 1 to protect golden eagles during their nesting season. These areas are located along State Highway 119 approximately 1.5 miles east of Boulder Falls.

Eagle Rock, Happy Hour, Security Risk, Bihedral, and Riviera are all open.

The closures help protect a long-established golden eagle nesting territory, including vital alternate nest sites. Undisturbed access to multiple nest sites is important for birds of prey, especially early in the nesting season, to give them a chance to visit multiple nests during courtship and to select a site for the season, free of human influence. “Closures in Boulder Canyon are vitally important to protect one of only a handful of known golden eagle nesting territories in Boulder County. Their specific habitat needs limit what areas they can use for mating and fledging their young,” said Sylvia Clark, Boulder District Ranger. Contact Boulder Ranger District at 303-541-2500 for more information.

Boulder Falls (City of Boulder) is closed indefinitely until flood damage is repaired.
