What U.S. mountain range is often referred to as the "American Alps" ?

The North Cascades are a section of the Cascade Range of western North America. They span the North Cascades and are considered the most rugged mountain range in the contiguous United States. The North Cascades are often referred as the "American Alps" by hikers, climbers, mountaineers and others who love the outdoors.

The bulk of the North Cascades consists of "deformed and metamorphosed, structurally complex pre-tertiary rocks". These originated in diverse locations all around the globe. The North Cascades are part of an area that is built of several ("perhaps ten or more") different terranes of different ages and origins.

Today the location called the "American Alps" is full of miles and miles of clever trails surrounded by very scenic natural areas. This region clearly offers hikers and climbers great opportunities to face steep and jagged peaks that span across vast mountain ranges. And, if you ever find that you want to have a memorable experience, accept the open-ended challenge and at some point go hiking or climbing in the North Cascades (the American Alps).
