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.

Comments
Comment (General): "Radioactivity anomaly in area of gray sandstone underlain by red, graysih red, and brown sandstone; no uranium minerals visible. (Bull. 1107H, Table 5, p. 641, #248)
Comment (Reference): Deleted ref. to "1147 SHARSRP ET AL" [sic]. The correct citation should be to Sharp and Gibbons, 1964, USGS Bull. 1147D. BUT, this study area is north of this location. Therefore it does not directly apply to this record.
