Location: The location of this occurrence is uncertain. The only description is that Big Four Creek is a left-limit tributary to Conglomerate Creek between Conglomerate Creek and Mascot Creek (Reed, 1938). This could be one of several left-limit tributaries to Conglomerate Creek. This location is arbitrarily placed near the mouth of the largest of the left-limit tributaries of Conglomerate Creek, at the east edge of the SE1/4 section 20, T. 31 N., R. 14 W., of the Fairbanks Meridian. Big Four Creek is given as an alternate name for Bonanza Creek in the U. S. Bureau of Mines Minerals Availability System data (U.S. Bureau of Mines, 2000). Their location also differs from Reed's (1938) location for Big Four Creek. The Reed location is used here.
