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 500 ft. The key counts the lines OpenStreetMap draws, not the resort's runs (its own list is on the run map). 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.
