|Current site name||Unnamed (south of Flat Creek)|
|Geographic coordinates:||-144.13263, 62.72968 (WGS84)|
|Relative position||The site consists of several occurrences near an unnamed prospect (Cobb, 1979 [OFR 79-1247, p. 30] on the north side of the center part of the broad ridge between Cobb Lakes and Flat Creek. The broad ridge was called the Grizzly Hills by Kirk Stanley (written communication, 2000). The prospects are about 0.4 miles, south-southwest of a prospect mapped by Richter (1966, fig. 5). It is within a broad lead-zinc geochemical anomaly defined by Richter (1966) and a nearly coincident, gold geochemical anomaly defined by WGM Inc. (WGM Inc., 1980; anomaly 3a). The locality is approximately the same as number 11 of Richter and Matson (1972), and number 27 of MacKevett and Holloway (1977). The occurrences are in the NE1/4SE1/4, section 17, T. 11 N,. R. 7 E., Copper River Meridian.|
