This map shows the corridor from Denver to Glenwood Springs and the surrounding mountains. It covers the Tenmile, Mosquito, Sawatch, Elk, and southern Gore Ranges, and the Front Range from Boulder to Colorado Springs. Boulder is at the top of the map and Buena Vista is at the bottom. From east to west it covers from Aurora to Glenwood Springs.

Every recreational site and area is shown: trailheads, picnic areas, campgrounds, fishing access sites, boat launch sites, and alpine and nordic ski areas. Every trail is shown, with the names of most trails as well.

The map is designed to have two different perspectives. From a distance the viewer sees only the landscape and major highways. But viewed close up the viewer sees thousands of individual items (named peaks, creeks, recreation sites, forest service roads, trails, etc.) not seen from a distance.

To give the map a three dimensional look, it uses hypsometric elevation coloring combined with shaded relief and six types of land cover: forest, sagebrush, cropland, grassland, wetland, and urban areas.
