Public land it sits in

On Wilderness Atlas →

This campground sits inside Boise National Forest.

Each unit is published as a centre point and an acreage rather than a boundary, so this section stands it in for a circle of the same area. Whether a campground is inside, and how far it is from one it is outside, are both approximate.
