Satelite View
MRDS mine locations are often very general, and in some cases are incorrect. Some mine remains have been covered or removed by modern industrial activity or by development of things like housing. The satellite view offers a quick glimpse as to whether the MRDS location corresponds to visible mine remains.

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.

Comments
Comment (Location): ALONG DRY CREEK ROAD, UPPER SNAKE RIVER, SALT RIVER RANGE. EAST OF OSMOND. Deleted MAS record 0560230153 notes that this may also be in Sec. 2, however, the occurrence in Sec. 2 has it's own entry.
Comment (Geology): PHOSPhATIC SHALE MEMBER. Phosphate rock contains 72.7% B.P.I. (Bull. 50, p. 148)
Comment (Workings): Martin (1994, p. 30) notes that "A completely collapsed mine portal and an extensive phosphate dump in the bed of Dry Creek are the only signs of past mining at the site. Other workings reported in the vicinity are so collapsed and eroded as to be virtually indistinguishable from the surronding countryside.
