[pct-l] mile 738.2 campsite? near Mulkey Pass

[Will M]

One of the guidebooks lists a campsite off of a faint corral trail at mile
738.2.

Does anyone know if this is accurate?

I'm trying to do a short camp and "slackpack" out of the Mulkey pass (near
trail pass) area near Mt. Whiteny and would like to get slightly further
south than Diaz Creek (mile 741)

Also, is there parking at Mulkey Pass Traihead?

Thanks,
