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 (Workings): THREE OPEN PITS (SNOOPER, DICKSON, RAINBOW-MOOSE); DIMENSIONS ABOVE ARE FOR MAIN PIT

Comment (Geology): DEPOSITS LOCALIZED AND PRESERVED BY SLUGGISH GROUNDWATER MOVEMENT IN ARE. THOSE CONDITIONS STILL PRESENT AS EVIDENCED BY ARTESIAN PRESSURE IN WELLS AND SPRINGS ISSUING FROM ECHO PARK FORMATION AND BY A PRESENT URANIUM CONTENT OF GROUNDWATER IN AREA AS HIGH AS 900 PPB.

Comment (Location): ON SAME PROPERTY AS RAINBOW-MOOSE PIT; ON NORTH SIDE OF MIDDLE TALLAHASSEE CREEK ; INFO FROM LAND.ST :1976

Comment (Production): FROM SNOOPER AND DICKSON PITS

Comment (Development): DISCOVERED BY DRILLING; WAS ONE OF THE FIRST FEW DISCOVERIES IN THE AREA

Comment (Deposit): THE DEPOSIT WAS ELONGATE ALONG ITS NW AXIS. THE DIP ALONG THAT AXIS WAS HORIZONTAL, WITH A "1 TO SEVERAL" DEGREE DIP TO THE SW ALONG ITS SHORT NE AXIS
