History

Native American Tribes, such as the Ute Indians, were the first known users of Hoosier Pass. However, The pass gets its modern name from the “Hoosier state” of Indiana, where many of the area’s first explorers had come from during the 1860’s.
Because of its location on the continental divide, Hoosier Pass became the location for Colorado’s first transbasin water diversion. In 1929, water on the divide’s western side was aggregated east to the town of Alma, the highest incorporated town in the United States. In 1951 the larger city of Colorado Springs purchased the rights to the water and installed a pipeline to deliver it 70 miles east of the divide.
