The high-altitude landscape of La Plata County, Colorado, is defined by the extraction history at the headwaters of the Dolores River. Mining activity is visible through sites like the Bushwhacker Mine and Graysill Mine near Bolam Pass, while the Spanish King Number 1 Mine and Doctor Bell Group Mine reflect the era's prospecting across the steep terrain. These sites were often accessed via primitive routes like Hermosa Pk Rd, which connects the rugged basins to lower elevations.
