A good note for first-time hikers on this route who are on decent:
Around 1 mile from the top, when in the steep Class 2-ish section on the backside of the bowl there's a Manker Flats sign (with no arrow). The sign sits at a junction to a use trail which drops straight down from the main trail into Goode Canyon where there's a particular point of historical interest down there. This vertical use trail is NOT the correct decent route back to Manker Flats. There have been reports of people requiring SAR after continuing down Goode Canyon and becoming lost near the bottom, realizing this isn't the way out and not knowing how to get out. The sign was probably placed at this junction for this reason, but without any direction indicator it's not a helpful sign at all.
So, when you see the sign on descent, keep heading on the nearly-level southward main trail that it parallels. NOT the vertical use trail.
