The Elkhorn is a manganese and iron mine located in Jefferson county, Washington.
About the MRDS Data:
All mine locations were obtained from the USGS Mineral Resources Data System. The locations and other information in this database have not been verified for accuracy. It should be assumed that all mines are on private property.
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): THE AREA IS UNDERLAIN BY BASALT LAVA FLOWS AND INTERCALATED TUFF AND RED ARGILLACEOUS LIMESTONE; MUCH OF THE BASALT IS ALTERED. PILLOW BASALT IS EXPOSED IN PLACES. THE BASALTIC FLOWS GENERALLY TREND NORTH AND STAND NEARLY VERITCAL; LOCALLY, THEY ARE GREATLY DEFORMED AND FRACTURED. THREE RED LIMESTONE BEDS AND INTERCALATED BASALTS FORM THREE OR MORE DISTINCT PARALLEL RIDGES EXTENDING FROM THE DOSEWALLIPS RIVER NORTHWARD TO THE TOP OF THE DIVIDE. THREE LIMESTONE INTERBEDS IN BASALT CONTAIN LENSES OF MANGANESE ORE, SOME AS MUCH AS 25 FT. THICK. THE CRESCENT FORMATION, WHICH HOSTS MANGANESE MINERALIZATION ON THE OLYMPIC PENNINSULA, CONSISTS OF PALEOCENE? AND EOCENE PILLOW BASALTS COMPOSITIONALLY SIMILAR TO OCEAN RIDGE BASALTS. ASSOCIATED PELAGIC LIMESTONES WERE DEPOSITED IN DEEP WATER (SNAVELY, 1987, P. 306-308). ; INFO.SRC : 1 PUB LIT
Comment (Location): ABOUT 3.5 MILES NORTHEAST OF THE MT JUPITER LOOKOUT. THE ELKHORN GROUP OF CLAIMS IS ON THE SOUTH SLOPE OF MOUNT CONSTANCE. THE CLAIMS ARE BOUNDED BY BULL ELK CREEK ON THE WEST, MINER'S CREEK ON THE EAST, AND THE DOSEWALLIPS RIVER ON THE SOUTH. THE PROPERTY IS REACHED FROM BRINNON ON US HIGHWAY 101 BY FOLLOWING THE ROAD ALONG THE DOSEWALLIPS RIVER WESTERLY FOR ABOUT 13 MILES. THE MAIN WORKINGS RANGE IN ELEVATION FROM 1200 TO 4200 FT.
Comment (Development): ECON.COM: PRODUCED IN THE 1940'S (DATA FROM USGS, MRDS, 1990).
