1955 Map of Pearl

USGS Topo · Published 1964

About this map

Pearl and its surrounding ranchlands reveal a landscape shaped by high-altitude mining and a complex network of irrigation during the mid-1950s. The presence of the Smelter Stack and named mining operations like the Zirkel Mine, Wolverine Mine, and Swede Group Mines points to an era of industrial extraction within the Routt National Forest. The geography is defined by its water management, featuring an Abandoned Aqueduct and numerous hand-cut waterways such as the Continental Ditch and Hans Clauson Ditch, which were essential for sustaining remote operations like the Wilford Ranch and Lobdell Ranch. The massive Big Creek Lakes anchor the western terrain, serving as a focal point for recreation at the Lakeside and Big Creek sites. This survey provides a precise record of the rugged North Park borderlands before modern development, tracing the intersection of the timberline, cattle ranching, and early 20th-century mineral claims.
