The Stevensville Ranger District is reminding people about the annual climbing closure in the Mill Creek area north of Hamilton to allow for nesting of cliff-dwelling raptors.
Several climbing routes are closed to prevent disturbance to these known raptor nesting sites.
On the north side of Mill Creek, the spring raptor closure will be the same as last year and includes the “Pie for Strength” climbing area.
The closure will be expanded this year to include cliffs on the south side of the canyon due to the presence of additional nests.
Maps will also be posted at area trail heads and on the Bitterroot National Forest website.
US Forest Service Wildlife Biologists plan to visit the area later this spring to determine the presence or absence of birds using the nests.
If the nests are not active, the restrictions will be lifted.
