Below are two Google Earth photos, and a Forest Service map showing trails of the area worked by the Beaver Patrol. The first photo shows where Beaver Patrol members often meet at the trailhead behind the Forest Service building. They then walk to other areas shown on both photos. The second photo continues to the east of the first to include Crystal Lake.
A few other areas are regularly monitored, but work at those locations is normally done by a single Beaver Patrol member.
