The satellite view offers a quick glimpse as to whether the MRDS location corresponds to visible mine remains.

Land ownership: Unknown
Note: the land ownership field only identifies whether the area the mine is in is generally on public lands like Forest Service or BLM land, or if it is in an area that is generally private property. It does not definitively identify property status, nor does it indicate claim status or whether an area is open to prospecting. Always respect private property.
