The trail is closed November 15 through March 15 to protect bald eagle roosting habitat and nesting. It is a historically, geologically and ecologically unique area. Two different rock types and vegetation zones intermingle. Columbia Plateau basalts and Okanogan Highlands granites are both present in Northrup Canyon having been exposed by glacial activity and by the Missoula floods erosion. Shrub-steppe habitat is adjacent to native pine forest and the trail follows a historic road.
