The Cumberland Gap Area is a titanium, metal mine located in Uinta county, Wyoming.
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 (General): Combined 6 separate records that cover 3 1/2 sections into one record, as described in Bull. 50, p. 196-197. Each of the sections is now separately listed in the PLSS location table. This is a mini "district" containing several small discontinuous deposits. But, coded this as a deposit, because it isn't really a district, just a report of Ti-potential.

Comment (Deposit): SAMPLES ALONG OUTCROPS HAD AVERAGE PERCENTAGES OF 1.7 TIO2, 0.1 ZRO2, 10.0 FE, AND LESS THAN 0.01 EQUIVALENT THO2. RELATIVE PERCENTAGES OF HEAVY MINERALS PRESENT, AS SHOWN BY 5 SAMPLES, ARE 78.4 OPAQUES, 10.6 ZIRCON, 7.2 CHLORITE (INCLUDING ALL MICACEOUS MINERALS), 1.6 ANATASE, AND 1.0 EACH GARNET, RUTILE, TOURMALINE, APATITE, MONAZITE, EPIDOTE, AND SPHENE. THESE ARE THE ONLY KNOWN DEPOSITS WHERE ANATASE OCCURS AS DISCRETE GRAINS AND IS PROBABLY AUTHIGENIC. THE POTENTIAL RESOURCES OF TITANIFEROUS SANDSTONE IN 19 WYOMING DEPOSITS, INCLUDING THE CUMBERLAND GAP AREA, ARE 21,873,000 ST WITH WEIGHTED AVERAGE GRADE PERCENTS OF 5.22 TIO2, 0.55 ZRO2, 24.75 FE, AND 0.15 EQUIVALENT THO2.
