About this map

Estes Park and Grand Lake serve as the primary gateways to this high-altitude landscape during the early years of the National Park era. Following surveys in 1912 and 1913, this map captures the region just as Rocky Mountain National Park was being established. The terrain is defined by its massive glacial features, including Sprague Glacier, Tyndall Glacier, and Andrews Glacier, which feed into a complex network of alpine waters like The Loch and Chasm Lake.

Evidence of early human passage and settlement is scattered throughout the peaks, from the historic Ute Trail and Milner Pass to localized hubs like Monarch PO, Allens Park, and the Sleepy Hollow School. To the west, the landscape drops toward Granby Mesa and Camp Ouray, while the eastern slopes transition into the mining and ranching interests near Ward. This document records a pivotal moment when seasonal tourism began to formalize around the natural wonders of the Continental Divide.
