Geology at Rochford
This spot sits on ground mapped as Metamorphosed tuffaceous shale, tuff, and volcaniclastic rocks that formed roughly 2500 to 1600 million years ago. Gold in volcanic terrain like this is usually tied to old vein systems and the gravels that drain them, so nearby washes tend to carry the color.

Public-land rules vary by agency, season, and field office. The RockHoundR app pulls live BLM, USFS, NPS, and tribal overlays so you can see exactly which agency manages the ground at this spot.
