As climate change reshapes seasonal patterns, ski resorts worldwide face a pressing challenge. Snowmaking has become a crucial tool for these resorts to ensure reliable snow cover in the face of rising temperatures and unpredictable snowfall patterns. Traditionally reliant on natural snow and early winter conditions, many resorts now employ innovative snow storage techniques, also known as “snow farming,” to help preserve snow over the summer months.
This practice, explored in the video “How Ski Resorts Store Snow Over the Summer” by Half as Interesting, involves stockpiling snow in insulated piles to minimize melting. This ensures slopes are ready for eager skiers at the start of the season. By employing methods like covering snow with wood chips, sawdust, or high-tech foam blankets, resorts can retain up to 70% of their snow, even in warm conditions.
“How Ski Resorts Store Snow Over the Summer”
The primary focus here is snow farming, a technique where resorts stockpile snow in insulated piles to combat melting. Ski resorts in the Alps and North America gather snow during winter, often using artificial snow machines to supplement natural snowfall. These piles are strategically placed in shaded areas or depressions to minimize exposure to the sun. Resorts then cover the snow with insulating materials, such as wood chips, sawdust, or specialized tarps. This can reduce melting by up to 80%. Some resorts, particularly in Europe, use advanced foam blankets with high albedo to reflect sunlight. The video highlights that this method allows resorts to retain 50-70% of stored snow. They can do this even in temperatures exceeding 20°C (68°F).
But this all has a cost. Environmental considerations are another key topic. Snow storage requires energy-intensive snowmaking, which raises concerns about water usage and carbon emissions. The video notes that resorts in water-scarce regions face challenges, as snowmaking can consume millions of gallons of water annually. However, stored snow reduces the need for excessive snowmaking in early winter, potentially offsetting some environmental costs. The discussion also touches on climate change, as warming temperatures make snow preservation critical for resorts at lower altitudes.
Economically, snow farming is a gamble. The upfront costs—such as snowmaking equipment, labor, and insulation materials—can be significant, often reaching hundreds of thousands of dollars. Yet, it ensures early-season openings, attracting skiers and boosting revenue. The video cites examples, such as Whistler Blackcomb, where reliable snow cover drives tourism and contributes billions to local economies.
