|Location and accuracy||Glacier Creek is a northeast-flowing stream on the east side of Monument Mountain. At least 4,000 feet of the creek has been placer mined. The center of this mined area is 11,200 feet southeast of the summit of Monument Mountain and 30,000 feet northeast of the summit of Kiwalik Mountain. The locality is about 1.3 miles upstream of the beginning of the Candle ditch. This is locality 60 of Cobb (1972; MF 417; 1975; OFR 75-429).|
Geologic descriptionPlacer gold was discovered in 1908 (Henshaw, 1909). Two men reportedly produced $400 (20 ounces) in 7 hours of mining from a 20 foot-wide paysteak in thin gravels. Apparently gold values have been found from the Candle ditch intake upstream for 1.5 miles but the mapped extent of placer workings start about a mile above the ditch. There are at least 4,000 feet of placer workings along the floodplain of the creek. Monument Mountain is underlain by a polydeformed metapelitic schist that may be Precambrian in age but the bedrock of Glacier Creek is a metasedimentary sequence of Lower Paleozoic age (Till and others, 1986). The Paleozoic metasedimentary rocks locally include felsic metavolcanic rocks in areas peripheral to Kiwalik Mountain. Float of very fine-grained, siliceous, tan-weathering metasediment (tuff or exhalite ?) has been observed in the headwater gravels of Glacier Creek (T. L. Hudson, unpublished data, 1982).
