Longs Peak and the high summits of the Mummy Range dominate the western horizon of this mid-century survey, where the alpine wilderness of Rocky Mountain National Park meets the expanding agricultural and academic corridor of the Front Range. The landscape is defined by the transition from the Medicine Bow Mountains to the high plains, irrigated by the Cache la Poudre River and Big Thompson River. This era shows the critical water infrastructure supporting the region, including Horsetooth Reservoir and Carter Lake, alongside the established rail networks of the Union Pacific RR and Colorado & Southern RR.
