It is about 2.2 miles along this sandy 4WD road to the junction with Horse Canyon on the left. The Salt Creek route continues on the right to Peekaboo Springs and the not to be missed pictograph.
I thought this arch was Paul Bunyan's Potty but it actually belongs to someone smaller and doesn't seem to have a name. Paul apparently has a two holer. It took me about 1:15 hours to get to this point. The canyon floor here is fairly dense with vegetation and there appears to be a project of reducing the invasive Tamarisk trees.
It is possible to get off the trail and down into the wash for a closer look. This area has a lot of alcoves and cave formations that look like possible ruins sites. The ruins sites in this area mostly appear to be small storage sites.
