|Current site name||Unnamed (in Glacier Basin)|
|Geographic coordinates:||-132.03878, 56.47975 (WGS84)|
|Relative position||Coordinates are for approximately the center of an elongated mineralized area of about 1 1/2 square mile in area that extends from Marsha Peak southeast to Glacier Basin. The area comprise most of the eastern half of sec. 19 and the western half of section 20, T. 62 S., R. 86 E.; it includes several small mineral occurrences and two prospect that are mapped in detail on Plate 9 of Gault and others (1953).|
