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 1,000 ft. The key counts the lines OpenStreetMap draws, not the resort's runs (its own list is on the run map); bowls and glades mapped as areas are a faint fill in their difficulty's color. The resort's glades and bowls are drawn as areas: OpenStreetMap's own where it maps one, otherwise drawn by Aurora around OpenStreetMap's line, up to 60 m each side and halfway to the next run or lift, so their edges are approximate.
