"Igloo building was an essential skill for the Inuit to survive the cold Arctic nights. Finding good 'igloo snow' is the first and most important part."

Our Colorado corespondent was on scene at several resorts this weekend as the lifts stopped turning (and the costumed ski freaks came out of the woodwork). Here are a few photos from the final day.

A waterproof shell and puffy jacket in one? We put the Eddie Bauer First Ascent BC MicroTherm to the test this winter in Colorado through a range of weather conditions and activities on the snow.

This winter, the editor of GearJunkie put his kids to task trying out new outerwear, mitts, boots, and miscellaneous cold-weather gear. Snow forts, skis, sleds, and icicle sword fights were involved in the test.

U.S. highway billboard vinyl is a thin, durable, and recyclable material. A new brand has built ski bags made of the material, which might otherwise end up in a landfill.

Sheep raised on the open pasturelands of the Rocky Mountains have tougher, more durable wool. That is the theory of a new Colorado company called Voormi. We tested a debut top from the brand this week skiing in the San Juans.

"Engineered for all seasons." That may sound like a flip tag line. But with a new tent, Easton thinks it has found a sweet spot between ultralight, three-season tents and burly winter shelters.

John Storkamp is no stranger to moving long distances over snow. During the coldest months the 33-year-old Minnesotan is often found pulling a sled full of survival gear across a frozen wilderness. Last month, he did it for 350 miles in Alaska.

Meier Skis, a Glenwood Springs, Colo., custom manufacturer, makes skis from beetle-killed pine trees. We gave the brand's all-mountain model a two-day trial test.

From Minnesota to Alaska, Salsa's "lightest and fastest fatbike" is winning major snow-bike races this season. We took a closer look at the Beargrease model, which weighs just 28.5 pounds in a stock complete build.
