Access Issue: 2025 Seasonal Raptor Closures - Triple Tier, Boston Peak, Grazing Allotment Crag Details

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.

From the Canyon Lakes Ranger District Forest Service:

Fort Collins, Colo. (March 7, 2024) – to protect nesting birds of prey, the U.S. Forest Service is implementing annual area closures in several popular recreation areas throughout the Canyon Lakes Ranger District.

Description

This is the crown jewel of the Grandpa's Bridge area. This intimidating dome was the inspiration to develop the entire area. This wall gets shade in the morning and sun in the afternoon. The rock is average for the most part, but the steepness, position and quality of movement make up for that.

Getting There

When the river is low or iced over, it is best to park on CO 14 in direct view of the wall. Cross the river, and walk up the leftside of the hill below the wall. A short 20 foot rappel on a fixed line gets you to the belay ledge.

When the water is high, park at the big pullout near the bridge, and walk along the river until you are below the wall. When the river is peaking, you may have a 2-3 week window where even wading along the river is impossible.

Descent: when you're done for the day, it is best to do a 30m rappel straight down the ledgy/slabby face using the 2-bolt anchor off the ledge.
