As of 8/4/18, This trail is now IMPASSABLE for four-wheeled vehicles.
This summer's storms have worn deep into several of the draws north of Devil's Chasm, but one of them, at the map below, is not navigable. The flowing water has pulled the draw in deeper and what used to be two trees that were just left of the approach, are now blocking the approach.
Motorbikes should still be ok to get through.
No idea what's north of there. Safe bet it's more storm damage and probably more blown out draws.
Rumor has it the feds or whoever oversees this shit, is no longer maintaining that road and it will stay as is...maybe even become officially closed soon.
