Identification information

Deposit ID 10003499
MRDS ID A106257
Record type Site
Current site name Theodore River

Geographic coordinates

Geographic coordinates: -150.99269, 61.34951 (WGS84)
Relative position MacKevett and Holloway (1977, locality 10) locate these placer prospects in the Theodore River and tributaries draining the south end of Little Mt. Susitna. Placer occurrences are noted in T.15 and16 N., R.9 and 10 W. for about ten miles along the Theodore River and tributaries to the northeast (U.S. Bureau of Mines, 1998, MAS # 0020840025 and U.S. Bureau of Mines, 1973, localities 25, 55a-e, and 73). Location is approximated in the mid section of the Theodore River.
