A 1:24,000 topographic map of Chicago Basin in Colorado’s San Juan Mountains, covering four 14ers: Mount Eolus (14,085 ft), North Eolus (14,040 ft), Sunlight Peak (14,059 ft) and Windom Peak (14,087 ft). Shaded relief with 200-foot and 40-foot contours from USGS lidar elevation data, with official trails, 4WD roads, lakes and streams, forest cover, and wilderness, national forest and private land boundaries. Sightline markers along the edges point toward other 14ers, with each one’s distance and bearing.
The margins give each summit’s coordinates, prominence and isolation, the Native lands it sits within, other names where they exist, and a short history. Elevations are from the 2024 NGS lidar survey. One of 31 maps in the Ridgeline Maps Colorado 14ers series, covering all 58 peaks. From Ridgeline Maps.
