Ruins of the lower Sahuarita Dam and an old coral along the Sahuarita Wash.
Cache is a good sized container, plenty of room for trades, hidden above one side of the ruined dam remains, probably not the side you park at !
Your route here will likely need a high clearance vehicle, the side road from the powerline road is no worse a condition, although that can change after rains, use your own judgement. Be aware of usual desert nasties.
This cache is on Arizona State trust land (ASTL) and a recreation permit is needed to geocache on (ASTL) Geocachers must purchase a permit available on the Arizona State land department website. You can get permits here:
