Seen as a trail map shows a mountain: from the base looking uphill, the ground tilted up (heights ×1.5); the arrow points north and the scale holds across the page. Runs and lifts as OpenStreetMap's contributors have mapped them, on the ground from USGS elevation data, with a stronger contour every 100 ft. The key counts the lines OpenStreetMap draws, not the resort's runs; bowls and glades mapped as areas are a faint fill in their difficulty's colour.
