There are more informal trails here, which will need to be mapped via GPS as they are not visible on aerial due to tree cover. Additionally, the creek path must be verified on the ground; its crossing with the GPS-tracked path is known to be accurate, but otherwise it is traced from National Map Topo

What is this? Tag appropriately

This construction is complete.

This road cannot be safely traversed as a pedestrian, but OSM will route a walking route on it. I am unsure if pedestrians are legally forbidden here, however, and I'm not sure how to tag this properly.

Someone put the speed limit as 15 here. This seems incorrect, but need to search for a speed limit sign on the ground to check
