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
No federal campground is within ten miles of the boundary in the Campsite Atlas index. Camping inside a wilderness is usually allowed away from trails and water, with no facilities; the managing agency page has the permit and group-size rules.
