1 mi. N of Aleknagik Lake and 28 mi. NW of Dillingham, Kilbuck- Kuskokwim Mts.
Name recommended by W. C. Mendenhall, U.S. Geological Survey (USGS), in 1932 and approved by Board on Geographic Names (BGN) over the name Mount Shasta. Jackknife Mtn. seems to have first been shown on an old manuscript sketch map made by (G. D.) Hanna, U.S. Bureau of Fisheries (USBF). Mount Shasta seems to have been predominant local usage around 1930, and was so called because of the resemblance of the mountain to California's Mount Shata.
