Gibbon is a station on the Union Pacific railroad that was named for Major General John Gibbon, who was in command of the Department of the Columbia based in Vancouver, Washington from 1885-1886. At the time the railroad was being constructed, there was a station at or near Gibbon named Mikecha, made up from the names of three civil engineers named Mink, Kennedy, and Chalk. At the beginning of the 20th century, the name of the station was changed to Bingham Springs, because it served the Bingham Springs resort, which is eight miles east up the Umatilla River. The name of the post office, however, remained Gibbon. Gibbon post office ran from 1892 through 1966. At some point the name of the railroad station was changed back to Gibbon. Today Gibbon has an Adams mailing address.
