of the Yukon River, between Roosevelt I. and mainland 12 mi. SSW of Russian Mission, Yukon-Kuskokwim Delta. 5.5 miles long.
Name shown on a 1940 navigation chart of the Yukon River. Because this chart was compiled by the Riverboat Service, The Alaska Railroad, U.S. Dept. of Interior, one can assume it was named for Harold L. Ickes, 1874-1952, Secretary of the U.S. Department of the Interior from 1933 to 1946. See Roosevelt Island.
