Boundary map
Boundary, simplified to about 0.005 degrees Federal campground
The outline is the agency boundary simplified for display, so small parcels and inholdings may not show. The agency page has the authoritative map.
Weather by month
Large units span more than one climate. The station stands in for the center point, and the outer parts of the boundary can be warmer or colder.
Where to camp
None of the 4 federal campgrounds within ten miles sit inside the boundary. Nearest first. Distances are from the campground point to the boundary edge, from the Campsite Atlas index.
Most refuges do not allow overnight camping. The campgrounds listed are outside the refuge.
