| Relative position | Martin and Katz (1912) reported that fine flour gold was present on gravel bars of the Mulchatna River above the mouth of the Koktalee (Koktuli) River. For this record, the location is a gravel bar about a mile above the mouth of the Koktuli River, arbitrarily chosen to represent the general area of occurrences noted by Martin and Katz (1912). Cobb (1972 [MF 375]; 1976 [OF 76-606]) included these occurrences under the name 'Mulchatna River'. |
