4 mi. NW of Mitlak Mtn. and 25 mi. N of Goodnews, Kilbuck-Kuskokwim Mts.
Local name obtained as "figure iv mountain" in 1898 from Reverend J. H. Romig, missionary, by J. E. Spurr and W. S. Post, U.S. Geological Survey (USGS). So called because the deep valleys on the mountain side, when filled with snow, form the numeral IV when seen from the west.
