History Nebraska marker No. 472, at a pull-out on the north side of NE 2 about 10 miles west of Mullen, marks the site of Hecla, a Burlington station named for Iceland’s Mount Hekla. Its post office opened in 1887; a store and lumberyard followed about 1911, the post office and school closed by the 1950s, and when the depot and stockyards were removed in 1967 the town ceased to exist.
