Eureka sits at the confluence of the Animas River and Eureka Gulch, serving as a central point in this high-altitude landscape where Hinsdale Co, Ouray Co, and San Juan Co converge. The topography is defined by extreme elevations and deep drainage systems like Grouse Gulch and California Gulch. This 2019 survey captures the complex network of mountain infrastructure, including the Bagley Tunnel and high-mountain crossings like Cinnamon Pass and Engineer Pass. Historical industrial activity is etched into the terrain through named features like Denver Bridge and the various basins—American Basin, Hurricane Basin, and Horseshoe Basin—that once supported prospecting and transport. The map provides clear detail of the Gunnison National Forest and Uncompahgre National Forest boundaries, illustrating how early trails like the Bear Creek NRT follow natural watercourses like Bear Creek through the steep southern San Juan Mountains.
