How we check the facts

Every fact on Ski the Andes comes from a primary source: the resort's own website, or an official tourism or government site such as chile.travel or a provincial or municipal tourism office in Argentina. We don't use blogs, travel agencies, review sites or other ski directories.

Each value is written as the source states it, with its season where it has one. When a resort publishes two different figures on different pages, we use the more specific or more recent page. When a resort doesn't publish a figure, the page says 'Not published by the resort'. We never estimate. The only values we calculate are vertical drops, when the resort publishes its top and base elevations but not the drop; those are marked.

A resort gets a page only when at least 10 of the 14 core facts are published by a primary source and the resort operated in the latest season. Resorts below that line are not listed.

Prices and season dates change every year. We re-check every fact before each southern winter and show the date of the last check on every page.
