History

edit

The town was founded in 1936 around a new high school.[6] [7] The school was finished in 1935.[8] A contest was held to name the school, and the winner was 10th-grade-boy Clarence Snyder. He created the portmanteau of Altamont, combining the names of the nearby villages of Altonah and Mount Emmons.[6][8] The community grew gradually and, in May 1953, petitioned to incorporate as a town in 1953.[8]
