The North Cascades are a section of the Cascade Range of western North America.They span the border between the Canadian province of British Columbia and the U.S. state of Washington and are officially named in the U.S. and Canada [1] as the Cascade Mountains. [2]
The Cascade Range or Cascades is a major mountain range of western North America, extending from southern British Columbia through Washington and Oregon to Northern California. It includes both non-volcanic mountains, such as many of those in the North Cascades , and the notable volcanoes known as the High Cascades .
As fronts approach the North Cascades, they are forced upward by the peaks of the Cascade Range (orographic lift), causing them to drop their moisture in the form of rain or snowfall onto the Cascades. As a result, the west side of the North Cascades experiences high precipitation, especially during the winter months in the form of snowfall. [7]
The Enchantments is a region within the Alpine Lakes Wilderness area of Washington state's Cascade Mountain Range. [2] At an elevation of 4,500 feet (1,372 m), it is home to over 700 alpine lakes and ponds surrounded by the vast peaks of Cashmere Crags, which rate among the best rock-climbing sites in the western United States.

Mount Ballard is an 8,371-foot (2,551-metre) double-summit mountain located in eastern Whatcom County of Washington state. [1] It is part of the Okanogan Range which is a sub-range of the North Cascades Range, and the mountain is situated on land administered by the Okanogan–Wenatchee National Forest.
The Cascade Mountains form the northern portion of the Cascade-Sierra province. The Cascades were created from thousands of small, short-lived volcanoes along the Cascadia subduction zone [5] that over millions of years built a foundation of lava and volcanic debris on which the mountains rise.
The North Cascades features some of the most rugged topography in the Cascade Range with craggy peaks and ridges, deep glacial valleys, and granite spires. Geological events occurring many years ago created the diverse topography and drastic elevation changes over the Cascade Range leading to the various climate differences.
The northern part of the mountain was destroyed in the blast (1980 Mount St. Helens eruption). Mount Adams (east of Mount St. Helens) — the second highest peak in Washington and third highest in the Cascade Range. Mount Hood (northern Oregon) — the highest peak in Oregon and arguably the most frequently climbed major peak in the Cascades.
