A field guide to Colorado's fifty-eight highest summits, drawn on the terrain itself.

The Fourteeners began as a simple question: what would it look like to see every one of Colorado's peaks above 14,000 feet rendered not as a photograph, but as the shape of the land itself? Each peak here is a 3D relief model built from real elevation data, with its standard route traced across the slope.

The result is somewhere between a map, a reference and a piece of type. Browse the full index, filter by range, and step into any summit to read its history and study the route in three dimensions.

This site renders Colorado's 58 recognized 14,000-foot peaks as interactive, to-scale 3D terrain rather than illustrated maps — 53 independently ranked summits plus 5 named sub-summits that fall short of the usual topographic-prominence threshold but are traditionally climbed and listed alongside them. Elevation comes from the USGS 3D Elevation Program's LiDAR-derived data, served through the AWS Terrain Tiles dataset; trails, lakes, and streams are drawn from OpenStreetMap via the Overpass API, the same open, crowd-verified geodata used across the site's other trail dioramas. Peaks that share a trailhead or ridgeline share one rendered terrain scene — the 58 peaks map to 33 scenes — so the underlying map data is never duplicated, only the page built around it. Type is set in Archivo and Space Mono.

Nothing here is a substitute for a guidebook, a map and good judgment in the field — it is a way to look, plan and get excited about the high country.
