Some confusion may occur from mistaken tributary names. Pass Creek on the USGS Lake Clark D-5 topographic map is labeled by Jasper (1961) as Cash Creek. Essentially part of the Bonanza Creek placer deposit.
Location: Prospect is along an east to southeast flowing tributary of Bonanza Creek. This locality is plotted according to Jasper's (1961) map of the Bonanza Creek area. The Pass Creek on the USGS Lake Clark D-5 topographic map is labeled by Jasper (1961) as Cash Creek. This is locality 8 of Cobb (1972) and locality 7 of MacKevett and Holloway (1977). NE1/4 sec. 34, T. 8 N., R. 31 W., of the Seward Meridian. Location accurate to within 800 m.
Geology: The Pass Creek is a placer gold deposit. Jasper (1961) reported: evidence indicates that glacial scouring was not an important erosional factor in this area, it is believed that pre-glacial alluvials were undisturbed, and that placer gold concentrations remain more or less as originally deposited along the creek . The valley surface width varies from 300 to 700 feet with an average width of 400 feet. The valley alluvials are mostly uniform gravels with some boulders, interpreted as reworked glacial deposits. Bedrock is shale, argillite, and graywacke cut by porphyritic granitic dikes. The sediments strike N 40 to 45 E, and dip varies from 60 to 75 SW.
Workings: Jasper (1961) reports a little ground sluicing. Pass (Cash) Creek reportedly (unconfirmed) has the coarsest gold in the Bonanza Creek area.
