Snow Secure snow storage shows its performance in Aspen - 85 % snow retention over the summer

Drone measurements by Aspen Snowmass show 85% of snow volume remained under the insulated mats through the Colorado summer.

SANTA FE, N.M., Sept. 24, 2026 /CNW/ -- Snow Secure's insulated mats have passed their first Colorado summer in a snow storage pilot project at Aspen.

Snow was covered at Aspen Snowmass in April, with Snow Secure's continuous temperature monitoring running from April 30 through August 31.

Demonstrating exceptional insulation efficiency, the insulation mats maintained a thermal gap of over 84°F—holding the snow surface at a stable, just-above-freezing 33.6°F even as temperatures on top peaked at nearly 118°F (averaging 61.8°F).

Drone measurements by Aspen management on August 31 showed 85% of the snow volume remaining under the mats. The measurements include both summer melt and the natural compression of the stored snow.

24/7 monitoring at Snowmass shows the conditions the insulation faced. Over the period, the temperature sensor on top of the mats averaged 61.8°F (16,5°C) and peaked at 118°F (47,8°C) in the Colorado summer sun.

Directly beneath the insulation, at the snow surface, the temperature averaged just 33.6°F (0,9°C).

"Resorts cannot control the autumn weather, but snow storage gives them another way to control when they have snow available. Insulation is what makes summer storage possible in demanding conditions. Effective insulation, combined with an integrated rain cover, keeps the snow protected through the summer," said Antti Lauslahti, CEO of Snow Secure.

Aspen Snowmass describes the pilot:

"As part of our industry-leading commitment to sustainability and climate resilience, Aspen Snowmass is piloting Snow Secure blanket technology at Buttermilk and Snowmass -- Colorado's first deployment of this proven European system. By covering existing snowpack through summer, we can reduce our reliance on early-season snowmaking, conserving water and energy while delivering a better guest experience from opening day. We'll monitor results throughout summer to inform how we scale this technology across our mountains in the future."

Snow Secure is scaling rapidly in North America, where more than ten ski resorts have adopted the patented system in two seasons. Worldwide, Snow Secure has completed more than 150 installations, and its insulated mat technology was named one of TIME's Best Inventions of 2025.

Snow Secure provides patented snow-storage systems for ski resorts. Combining Finnish engineering with practical mountain-operations expertise, the company provides snow storage validation, planning and larger-scale master planning for ski resorts. In North America, Snow Secure works with SMI Snow Makers as its distribution partner for new ski resort projects.
