So took El Oso west of the "main" road (just north of Pigeon Springs road). Went down to Big Pine spring then headed west again, past the El Oso Mine with the intention of making the loop back to the Mazatal Divide trail. Not too far past the old mine, the road got fun. A litter further it got nasty, then, making the climb back up just before Mazatal Trail - I had to back out then turn around. The road was REALLY washed out. I probably could have made it through but tire placement needed to be perfect or I would have dropped 3+ feet into the V, that was past my solo wheeling comfort level. So, who's up to run this through?
It got a lot deeper and a bit wider with a few rock walls after this.
