1907 Map of Mount Olympus

About this map

The Big Thompson River and its labyrinthine drainage system define this 1905 survey of the northern Front Range. Surveyed by Frank Tweedy, the landscape reveals an early 20th-century economy transitioning from mountain ranching to early alpine tourism. Notable family holdings and early settlements like Dunraven Ranch, Plum's Ranch, and Meadowdale Ranch are scattered across the high parks and valleys, while the Rustic Hotel and Lovelind Heights suggest the area's emerging role as a destination. The terrain is dominated by the massif of Mt Olympus and the broad, high-elevation flats of Rattlesnake Park and Pierson Park. The southern portion of the map captures the transition across the Larimer Co Boulder Co boundary line, where the topography descends toward the eastern foothills near Noland and Miners Ranch.
