Map of Unalakleet Area

USGS Unalakleet D-4 quadrangle

Map of Unalakleet area, USGS Unalakleet D-4 quadrangle, 1950, with minor revisions in 1965. Squares are sections, 1 mile on a side, and elevations are in feet. Exact river channels and cultural features are probably out of date, but topography should still be accurate.

Unalakleet Station History

Located on shore of Norton Sound at mouth of Unalakleet River. Current coordinates 63 degrees 53' N, 160 degrees 48' W, elevation 18 feet; AAG map 131. Official record 1930 - present, but large amounts of missing data before mid 40's and after late 70's.

Opened at 63 degrees 54' N, 160 degrees 47' W, 30 feet elevation 11/1/36 with non- standard instruments and very poor documentation. Observer change and possible move 5/1/41; standard instruments at that time with temperature measured 5 feet above ground. Another possible move 6/6/43 when Army Air Force became observer. Coordinates change to current values except elevation 14 feet 11/14/45 but move still listed as unknown distance and direction. Thermometers lowered to 4 feet 8/1/54. USWB took over 6/22/67 with 1 foot increase in elevation but no recorded horizontal move. Slight move SW and 3 feet increase in elevation 10/15/82, thermometers raised to 5 feet.

Observation time midnight starting 6/6/43, changed to 2 pm 10/25/76.

Observer since 1967 USWS, FAA/CAA 1945-67; Army and coop earlier.

Record length short, data continuity good only from mid 40's to early 70's, site continuity virtually undocumented. Probably not worth using.
