The locality is in the Wrangell-Saint Elias National Park and Preserve.
Location: Young Creek is an east tributary to the Nizina River and the main drainage on the north side of MacColl Ridge. Placer gold has been recovered from the creek from an elevation of 2,400 feet (McCarthy A-5 quadrangle) to 3,000 feet (McCarthy A-4 quadrangle). Small tributaries, especially Calamity Gulch, have also produced gold. The location used here is the confluence of Young Creek and Calamity Gulch in the northwest corner of section 34, T. 7 S., R. 16 E. of the Copper River Meridian. This is locality 37 of MacKevett (1976). Cobb and MacKevett (1980) included this mine under the name 'Young Cr.'. It is accurately located.
Geology: Placer gold and some native copper nuggets have been recovered locally along Young Creek from an elevation of 2,400 feet in the McCarthy A-5 quadrangle to an elevation of 3,000 feet in the McCarthy A-4 quadrangle (MacKevett, 1976). Small tributaries, especially Calamity Gulch, also produced gold. Young Creek reworks glaciofluvial deposits and is incised into Cretaceous mudstone and siltstone (MacKevett, 1973). Prospecting occurred as early as 1909 and and there was intermittent small-scale surface mining or several years in the early 1900s (Moffit and Capps, 1911; Cobb and MacKevett, 1980).
Workings: Prospecting occurred as early as 1909 and and there was intermittent small-scale surface mining or several years in the early 1900s (Moffit and Capps, 1911; Cobb and MacKevett, 1980).
Age: Quaternary.
