It’s ski season in the Andes Mountains, and things are finally starting to fill in. The Southern half is a great way to get some powder turns in during your offseason!

The snowpack in the Andes is as inconsistent as it gets. Some years it is blessed with constant snow cycles, and other years resorts struggle to open for the season. But every so often, the Andes are blessed with storms that drop hundreds of inches of snow in a matter of days. Here are some of the deepest years on record in the Andes Mountains:

Historical Snowfall

1965

On August 9 and August 16, 1965, a storm that moved in from the Pacific Ocean dumped almost 20 feet of snow on the Chilean Andes and triggered avalanches that destroyed entire towns. By the time the storm had ended seven days later, Ski Portillo had lost every chair lift on the mountain.

2015

One of the largest snowstorms in South American history rolled through the Andes mountains of Chile and Argentina in early June 2015 and dropped up to 10 feet of snow in seven days. The storm closed the Los Libertadores Pass between Santiago, Chile, and Mendoza, Argentina, for 15 days. Totals on the Los Libertadores Pass were over 13 feet deep.

2020

While the world was shut down in the summer of 2020, Chile was experiencing one of its best winters in decades. Mendoza City, Argentina, recorded five feet of snow, which is the highest amount of snow ever recorded in the city that early in the season, according to the Argentine National Weather Service. Corralco in Chile registered snow totals in excess of 13 feet during the first week of July. Experts have said that this is the most snow Argentina has ever seen this early in the season.

Located in the Andes Mountains of Chile by the legendary Lake of the Inca, Ski Portillo is known for its steep and expert terrain similar to the Alps.

Las Lenas, Argentina 

Average Snowfall: 167 in 

Current Snowfall: 70 in

Elevation: 7,349-11,254 ft

Las Lenas Resort has some gnarly terrain. Which is why it attracts pro skiers from across the world. With more than 18,000 acres of skiable terrain, Las Leñas is one of the biggest ski resorts in South America. What makes Las Lenas special is the Marte Chairlift, a slow double chair that gives you access to 3,936 vertical feet at an elevation of 11,254. It’s a real playground for experts.

South America is home to the longest mountain range on Earth. The Andes gets big snow, and it has some of the highest mountains in the world outside the Himalayas along with some of the best skiing around.  The South American powder machine runs during the northern hemisphere’s hot summer months, so if ur looking to rip powder in July,  you gotta get down there.
