Geologic information

Identification information

Deposit ID 10307750
Record type Site
Current site name Gagaryah River

Geographic coordinates

Geographic coordinates: -155.0848, 61.66604 (WGS84)
Relative position Occurrences of placer gold and cinnabar are present in a several-square-mile area in uplands at the south end of the Lyman Hills and north of the Gagaryah River (Eppinger, 1993). The map site is at an elevation of 1,300 feet on a south-flowing tributary to the Gagaryah River in the SW1/4 section 4, T 18 N, R 32 W, of the Seward Meridian. The map site is chosen to represent the general area of gold and cinnabar occurrences.
