About this trail's facts

The lines are the US Fish and Wildlife Service's refuge trails inventory (public domain), read 2026-10-16 and simplified for the map; the length is the Service's trail mileage where it gives one, else the sections' sum; the surface, class, condition, uses, width, slope, dogs, bicycles and accessibility are the Service's own entries, and where a trail begins is the Service's own start point and words for it. The Service publishes no trailhead points for the refuges. Heights come from USGS 3DEP through Terrain Tiles on AWS (Mapzen/Tilezen), read along each line and rounded; a short trail on steep ground can be off by a few tens of feet. Closures change: check the refuge's own site before you go.
