It actually matches community GPS traces fairly well as currently mapped. Some areas diverge a little, but nothing I'd call significant on the eastern part of the trail

OSM prefers crowdsourced ground truth over government data (when we can get it, that is). Feel free to add other missing trails based on Forest Service data, but expect it to be updated as people follow the trails and collect ground truth.

Open the Map Layers panel, and enable the "Public GPS Traces" checkbox to see what I mean.

What concerns me is not the geometry but how it's tagged as highway=footway even though it's a minimally developed nature trail. I think highway=path would be better with trail_visibility=intermediate (or even =bad maybe)?

Also, and I don't know the consensus for this, it should have the name Cove Hollow somewhere tagged on it.
