Location and accuracy This occurrence is at an elevation of 2,500 feet, on a south-facing ridge approximately 3.5 miles south-southwest of Baldry Mountain and 3 miles northwest of Eureka Dome. The site is at Alaska Division of Geological and Geophysical Surveys (ADGGS) sample station 96RB038 (Liss and others, 1997), near the east edge of the southeast quarter of section 13, T. 5 N., R. 14 W., of the Fairbanks Meridian. The location is accurate within 500 feet.

Geologic setting

Geologic description

Bedrock in the Granite Creek area consists of Proterozoic(?) or Lower Cambrian(?) cherty argillite, chert, greenstone, and limestone in thrust fault contact with Ordovician chert, cherty argillite, limestone, and basaltic to intermediate metavolcanic rocks (Reifenstuhl and others, 1997 [PDF 97-15a]). No plutonic rocks are mapped in the local area. The rocks are cut by northwest-trending thrust faults and northeast- and northwest-trending high-angle faults.
A sample (96RB038) of argillite interbedded with limy mudstone on a ridge between Baldry Mountain and Eureka Dome contained 422 parts per million (ppm) zinc and 457 ppm arsenic (Liss and others, 1997). There is no record of exploration or mining at this site.
