Boundary map
Boundary, simplified to about 0.005 degrees
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.
This unit has no confirmed official page or nearby campgrounds in the sources this site reads. The boundary, size, agency and location above come from the agency layer.
The sources are read again every Sunday.
