The Henry Creek (including Merrit Gulch) is a gold mine located in Alaska.
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 (Exploration): Status = Inactive
Comment (Geology): Geologic Description = Gold was identified in Henry Creek gravels as early as 1901 (Collier, 1902) and some sporadic mining activity was noted up to 1937 (Smith, 1939, B 910A). Sainsbury and others (1969) show placer mine workings to be at two locations on this drainage. The first is a 1,500 foot-long segment of the active channel and an adjacent gulch on the north side that starts 4,000 feet upstream of the mouth. The second is another 1,500 foot-long segment of the active channel that starts 7,000 feet above the mouth. The gold recovered from early work was reported to be relatively coarse and flat (Collier and others, 1908). Bedrock of the area is extensively coverd by tundra, but upland exposures are primarily Lower Paleozoic metasedimentary rocks (Sainsbury and others, 1969; Till and others, 1986). A report of schist bedrock with enclosed greenstone bodies (Collier and others, 1908) refers to the mafic metavolcanic assemblage in the headwater areas of Henry Creek (Sainsbury and others, 1969; Till and others, 1986).
