Found this trail by accident yesterday (didn’t have on x until today). Generally smooth gravel with some small patches of washboard. Only saw two vehicles

Trail was slightly muddy with two passable wash outs at 4 and 4.5 miles in. Nasty snow bank at about 6.5 miles in; turned around and got stuck in a previous snow bank I was able to traverse. Super fun until it wasn’t! Will be returning when the snow melts to explore the rest.
