Mosier Ponds PWA

Hi. I was considering a trip to Mosier Ponds in the Pepperbox WA at some point. Anyone have experience in this area, would it be a decent area to set up camp for a night or two?

Also, which Ponds are considered Mosier? I see there are two decent sized Ponds near each other on map, then a larger pond to the north (SEof Duck Pond). Is this larger one considered one of them?

Any info on the area appreciated. Thanks!
