From the NFS (2/3/25): Seasonal restrictions to protect nesting birds of prey
FORT COLLINS, Colo. (Feb. 3, 2025) – To protect nesting birds of prey, the Roosevelt National Forest began implementing annual closures in several popular recreation areas within the Canyon Lakes and Boulder Ranger Districts on Feb 1, 2025.
On the Canyon Lakes Ranger District, the closure areas include Triple Tier, south of CO Highway 14; Boston Peak, north of CO Highway 14; Grazing Allotment Crag, northwest of Prairie Divide Road; and Mt. Olympus, southeast of US Highway 34. See the closure map for more details.
The Roosevelt National Forest works closely with partners like Colorado Parks and Wildlife, Boulder Climbing Community and the Northern Colorado Climbers Coalition to monitor nesting progress and inform climbers about the importance of giving raptors space to raise their young.
Federal and state laws prohibit disturbing any nesting bird of prey. Visitors can help protect wildlife by respecting all closures. Signs will be posted at key access points into the closed areas. Additional closure information is available online.
