|Location and accuracy||Quartz Creek is approximately 9 miles long and is an east-flowing tributary of the Sulatna River. No exact location of prospecting along the creek is known; coordinates are arbitrarily placed at the approximate midpoint of the creek, in section 31, T. 13 S., R. 19 E. of the Kateel River meridian. The location is accurate within 5 miles.|
Geologic descriptionThe drainage of Quartz Creek is along a thrust fault separating phyllite and quartzite of the Ruby terrane from pelitic schist of the Ruby terrane (Puchner and others, 1998). Intermediate to mafic intrusive rocks are also found at the uppermost headwaters of the creek (Puchner and others, 1998). Quartz Creek was prospected during 1912 (Eakin, 1913). The ground along the creek is as much as 180 feet deep and nearly all frozen (Eakin, 1914 [B578]). No mention of the creek is made in more recent reports.
