1919 Map of Rocky Mountain National Park

About this map

Monarch PO and the Denver and Rio Grande RR corridor represent the early 20th-century development of the Colorado high country just as Rocky Mountain National Park was established. The map depicts a landscape where traditional transit routes like the Ute Trail and the Grand Lake Trail intersect with modern engineering feats such as the Fall River Road. This era shows the convergence of alpine conservation and pioneer infrastructure, where remote outposts like Sleepy Hollow School and Camp Ouray served small populations in the shadows of the Medicine Bow Mts and Nokhu Crags. Water systems define the terrain, from the high Poudre Lakes at the Continental Divide to the lower elevation Stillwater Creek and Illinois River. The map captures the region when Grand Lake was becoming a focal point for recreation while nearby Granby and Coulter remained vital transit links for the ranching and rail economy.
