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 (Location): ON DIVIDE BETWEEN LAKE GULCH AND GOOSE CREEK 1.1 MILE NW OF DUBOIS MINE. ; INFO FROM LAND.ST :1975
Comment (Deposit): THORIUM VEINS IN THIS AREA ARE ONE OF FOUR ENVIRONMENTS OF TH OCCURRENCE KNOWN IN POWDERHORN-IRON HILL AREA AND ARE PROBABLY RELATED TO EMPLACEMENT OF LATE PRECAMBRIAN SYENITES NORTH AND WEST OF IRON HILL AND OF YOUNGER LATE PRECAMBRIAN OR CAMBRIAN CARBONATITES AT IRON HILL. FOLIATION OF BLACK CANYON SCHIST COUNTRY ROCK TRENDS GENERALLY N 57 TO 67 E, 85 TO 90 SE. FAULT TRENDING N 58 E DISPLACES SCHIST ON NW AGAINST POWDERHORN GRANITE ON SE. GRANITE FOLIATION NEAR FAULT TRENDS GENERALLY N 55 E, 85 TO 90 SE. SECOND FAULT TRENDS N 57 W, DIPS 85 NE, AND IS MAPPED AS QUARTZ VEIN WHERE IT INTERSECTS NE-TRENDING FAULT. FAULT INTERSECTION AND EXTENSIONS OBSCURED BY OLIGOCENE TUFFS.
Comment (Workings): TWO SURFACE PROSPECT PITS
Comment (Geology): OTHER MINERALS LISTED ABOVE ARE GENERAL OCCURRENCES REPORTED FOR TH VEINS IN AREA; ALL MAY NOT NECESSARILY OCCUR AT THIS SITE.
