Relative position | The Hot Air Bench placer is on the north side of lower Glacier Creek. The coordinates are for the approximate midpoint of an open-cut mine 900 feet north-northwest of the mouth of Snow Gulch on the Columbia claim of the Hot Air Mining Company (U.S. Mineral Survey No. 403). The bench placer trends west-southwest, subparallel to Glacier Creek. It is included in locality 101 of Cobb (1972 [MF 463], 1978 [OFR 78-93]). Hummel's (1962 [MF 247]) locality 7 is incorrect. The map location is in the NE1/4 section 26, T. 10 S., R. 34 W., Kateel River Meridian, and it is accurate to within 250 feet. |
