the large open area is actually AZ State Trust land and you need a $15/$20 permit, unless you go out to the BLM. Close to I15 so noisy, but cell signal is good. Area by hwy ramp is just a dumping trash area and a semi-parking overnite area, but the smaller two track roads meander out to better sites. The main graded road is the mine haul access so expect large trucks hauling gypsum?
