About this map

Lyons serves as the focal point of this 1968 landscape, situated where North St Vrain Creek and South St Vrain Creek converge. The town's industrial character is marked by numerous Quarries and gravel pits, reflecting the importance of stone extraction to the local economy. Further west, the terrain rises sharply into the Roosevelt National Forest, dominated by peaks like Steamboat Mountain and Indian Lookout Mountain. The infrastructure of water management is visible through the Button Rock Reservoir and the St Vrain Supply Tunnel, which underscore the region's reliance on managed water resources for agriculture and local utility. To the south, the settlement of Altona sits near Table Mountain, while the winding St Vrain Supply Canal traces the base of the foothills, illustrating the complex engineering required to move water across this varied topography.
