Mine Info
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 (Deposit): QUARTZ VEIN IN CROSS-CUTTING FAULT STRUCTURE. VEIN IS COMPOSED OF BRECCIATED WHITE QUARTZ AND QUARTZITE BRECCIA
Comment (Deposit): THE PLAYA IS NEARLY CIRCULAR IN OUTLINE AND HAS AN AREA OF ABOUT 30 SQUARE MILES. THE TOTAL RELIEF OVER THE AREA OF THE PLAYA IS LESS THAN 20 FT. THE SURFACE IS GENERALLY DRY AND ROUGH OR HUMMOCKY AND SALINE MINERALS ARE GENERALLY LACKING AT THE SURFACE EXCEPT IN THE AREA OF THE EARLY BORATE WORKINGS. ULEXITE FORMS COTTON BALLS IN THIN LAYERS 1-6 INCHES BELOW THE SURFACE IN IRREGULAR AREAS AROUND THE MARGIN OF THE PLAYA.
Comment (Location): UTM IS FOR MAJOR BORAX PLANT LOCATED IN SOUTHERN PART OF THE MARSH, BUT THE ACTUAL DEPOSIT COVERS MANY SQUARE MILES. INFO FROM LAND.ST :1972
Comment (Workings): SMALL CAVED ADIT WITH SOME SULFIDES ON DUMP; PROSPECT PIT
Comment (Geology): SAMPE 1918 TAKEN FROM DUMP AND SHEAR ZONE
Comment (Development): LOCATED AS A SALT DEPOSIT IN 1864. ULEXITE WAS DISCOVERED IN 1871, AND WITHIN A FEW YEARS, A NUMBER OF TREATMENT PLANTS WERE ACTIVE (4 BORAX COMPANIES). THE PACIFIC BORAX CO. MOVED ITS PLANT TO FISH LAKE VALLEY IN 1875, AND THE TOWN OF COLUMBUS DECLINED RAPIDLY THEREATER. EXPERIMENTS CARRIED OUT BY THE U.S.G.S. IN 1912 & 1913 SHOW POTASH PRESENT IS NOT IN COMMERCIAL AMOUNTS. DRILLING FOR POTASH OCCURRED IN 1912 AND 1913. ; ECON.COM: BORAX WAS PRODUCED AT COLUMBUS MARSH BY AT LEAST 4 COMPANIES, INCLUDING PACIFIC BORAX CO.

Comment (Location): 1.35 AIRMILES S75E FROM RAINSTORM GROUP ; INFO FROM LAND.ST :(1972)
Comment (Workings): SURFACE WORKINGS, PITS, AUGER HOLES (14 IN ALL) . REMAINS OF 9 BORAX WORKS, MOST ALONG THE N AND S EDGES OF THE MARSH. THE SALT WORKS WERE AT THE NORTHERN EDGE OF THE MARSH.
Comment (Deposit): IN 1875, THE TOWN OF COLUMBUS ON THE NW EDGE OF THE MARSH HAD A POPULATION OF 1000 AND A NEWSPAPER, THE BORAX MINER. BY 1881, HOWEVER, THE POPULATION HAD DWINDLED TO 100. A TOTAL OF 14 AUGER HOLES WERE DRILLED TO 50 FEET DEEP BUT FOUND NO COMMERCIAL AMOUNTS OF POTASH. IN 1913 THE PRESIDENT OF THE U.S. WITHDREW ALL PUBLIC LAND ON COLUMBUS MARSH FROM LOCATION FOR SALINGS UNDER THE FEDERAL MINING LAW. THIS RECORD CONTAINS DATA FROM DUPLICATE RECORDS I000501 OF G. ORRIS AND M035564 OF J.B. FIEBELKORN WHICH HAVE BEEN DELETED FROM MRDS. ; INFO.SRC : 1 PUB LIT
