1968 Map of Lyons

About this map

Lyons sits at the confluence of the north and south branches of St Vrain Creek, serving as a gateway to the mountainous terrain of the Roosevelt National Forest to the west. This 1968 revision reveals a landscape heavily shaped by water management and resource extraction, with the Longmont Powerplant, an aqueduct, and the St Vrain Supply Canal tracing the steep topography. Numerous quarries and mines are scattered throughout the foothills, particularly around Steamboat Mountain and Indian Lookout Mountain, illustrating the region's industrial foundations. Further south, the map details smaller settlements like Altona and Grange near Table Mountain. Infrastructure for the growing front range is evident in the Button Rock Reservoir and Longmont Reservoir, while a complex network of ditches like the South Ledge Ditch and Crocker Ditch supports local agriculture and water distribution.
