Prints of real mountains, or of your own route, drawn from open elevation data.
Elevation from Mapzen/Tilezen Terrain Tiles on AWS Open Data (SRTM, EU-DEM, UK Environment Agency LiDAR and others); summit names © OpenStreetMap contributors via Overpass; search by Nominatim. Skylines allow for the curve of the earth and normal refraction. The credit line on each print is required by the data licences.
