⎪THE CONTINENTAL UNITED STATES

Adirondacks, Cascades, Beartooths, Sawtooths, Sierras, Wasatch, White Mountains


Though compact, the Sawtooths in central Idaho are big in feel, quite remote, and super aesthetic. The Beartooths of Montana are similarly impressive, but take up a larger area and are even harder to access. Both mimic the high angles and snow quality found in the Tetons of Wyoming. The Sierras are rugged and beautiful, and are well known for their heavy and consistent snowfalls. The Cascades get even more snow, and is the only mountain range in the continental United States with any meaningful glaciated terrain. Due to its more consistent temperatures, and the high water content of its snowpack, both the Sierras and Cascades are a little less prone to avalanche than are most other mountain ranges in the U.S. But this relative stability can sometimes make for poor snow quality, as both the water content and relatively warm temperatures tend to produce higher levels of snow density. Fortunately, this presents less of a problem in steep terrain, which is fairly abundant here. The Wasatch Range (pictured above) just to the east—and leeward side—of the Great Salt Lake Desert in Utah, has fantastic terrain and some of the driest powder conditions in the Continental United States. Unfortunately, its Intermountain snowpack is extremely unstable and thus prone to avalanche. Global warming is also threatening its historic reputation for abundant and consistent snowfall. The White Mountains in the eastern U.S. have some of the nation’s worst weather (cold, windy and humid), and outside of the central Adirondacks in northern New York (and a few isolated spots in the Green Mountains of Vermont), are the only range east of the Mississippi River that features terrain suitable enough for serious backcountry skiing. The thin snowpack and gentle topography of the region (White Mountains) doesn’t allow for much excitement, but its modest verticals and high elevation-like conditions provide an excellent introduction to the sport. The twin ravines below the summit of Mt. Washington in New Hampshire (the East’s highest) are the region’s pièce de résistance.

  • The Rocky Mountains dominate the high ground of most of the western half of the United States. They are oriented north and south and cover a vast area from western Texas all the way to the Canadian provinces of Alberta and British Columbia. The Colorado Rockies and Wasatch make up most of the south and central areas within this region, while the Tetons, Beartooths, Absarokas, and Sawtooths take up the northern ones. The Sierras have a similar N-S orientation but are concentrated along the western coast (in California and Nevada), and sandwiched between the Central Valley on the west and the Great Basin to the east. The Cascades are an incongruous band of mountains contained within the northwest corner of the United States within the borders of Oregon and Washington. They are largely volcanic and often glaciated. The Appalachians are the obvious line of mountains in the east, starting in western North Carolina and on up towards the northeast corner of the States, ending in New York, Vermont, Massachusetts, New Hampshire, and Maine. While the terrain in the NE is relatively low, and not much higher in elevation than in the southern part of the range, their latitude makes for good skiing and snowboarding in winter, especially in the Adirondacks of New York and the White Mountains of New Hampshire.
