Searching for a country or continent yields the top 10 ski resorts in that area. The score is based on multiple criteria, like the quality of the snow and accommodations.
A higher scoring resort will have a bigger snowcap.
Resorts with greater average altitudes are represented by a higher mountain.
Resorts with a greater average difficulty appear steeper. This is calculated by combining the lengths of slopes adequate to advanced skiers only, and expressing that as a fraction of the total ski area.
