1972 Map of Lake Helena

About this map

Lake Helena and the Missouri River corridor define this 1970s landscape northeast of the state capital. The irrigation and water management infrastructure of the valley is evident through the Helena Valley Canal, Floweree Canal, and the Helena Valley Regulating Reservoir. Local social centers are well-documented, including the Masonic Home and the Community Center, alongside rural education sites like Mountain View Sch and Warren Sch. Toward the northeast, the terrain shifts near Hauser Lake, where evidence of extraction appears at several Prospects and a Mine. The map captures a mix of established residential patterns at the Trailer Park and agricultural transport along York Road and Lincoln Road East, illustrating the functional layout of the valley before late-century suburban expansion.
