Luahna Peak is an 8,400+ ft (2,560+ m) double summit mountain located in the Glacier Peak Wilderness of the North Cascades in Washington state. The true summit is 7400+ feet in elevation, and the northwest subpeak is 8,320+ feet. [1] The mountain is situated in Chelan County, in the Wenatchee National Forest. Luahna Peak is the second highest in the Dakobed Range after Clark Mountain which is 1.04 mi (1.67 km) to the southeast, and Luahna lies 6.95 mi (11.18 km) southeast of Glacier Peak. [1] The Richardson Glacier lies to the southeast of the summit, with the Pilz Glacier and Butterfly Glacier stretching across the northern slope. Precipitation runoff from the peak drains into the White River and Napeequa River, both tributaries of the Wenatchee River.
The North Cascades features some of the most rugged topography in the Cascade Range with craggy peaks, spires, ridges, and deep glacial valleys. Geological events occurring many years ago created the diverse topography and drastic elevation changes over the Cascade Range leading to various climate differences.
The history of the formation of the Cascade Mountains dates back millions of years ago to the late Eocene Epoch. [3] With the North American Plate overriding the Pacific Plate, episodes of volcanic igneous activity persisted. [3] In addition, small fragments of the oceanic and continental lithosphere called terranes created the North Cascades about 50 million years ago. [3]
During the Pleistocene period dating back over two million years ago, glaciation advancing and retreating repeatedly scoured the landscape leaving deposits of rock debris. [3] The U-shaped cross section of the river valleys is a result of recent glaciation. Uplift and faulting in combination with glaciation have been the dominant processes which have created the tall peaks and deep valleys of the North Cascades area.
Luahna Peak is located in the marine west coast climate zone of western North America. [4] Most weather fronts originate in the Pacific Ocean, and travel northeast toward the Cascade Mountains. As fronts approach the North Cascades, they are forced upward by the peaks of the Cascade Range, causing them to drop their moisture in the form of rain or snowfall onto the Cascades (Orographic lift). As a result, Luahna Peak experiences high precipitation, especially during the winter months in the form of snowfall which feeds its glaciers. [4] During winter months, weather is usually cloudy, but, due to high pressure systems over the Pacific Ocean that intensify during summer months, there is often little or no cloud cover during the summer with optimum weather for climbing Luahna from July through September.
Azurite Peak is an 8,400-foot (2,600-metre) double-summit mountain located at the common boundary point of Okanogan County, Skagit County, and Whatcom County in Washington state. It is part of the Okanogan Range which is a sub-range of the North Cascades Range. Azurite Peak is situated north of Azurite Pass on land administered by the Okanogan–Wenatchee National Forest. The nearest higher neighbor is Tower Mountain, 5.24 miles (8.43 km) to the south-southeast, and Mount Ballard lies 1.97 miles (3.17 km) to the north. Remnants of a small pocket glacier are found on the east aspect. The Pacific Crest Trail traverses the base of Azurite Peak.
Little Annapurna is an 8,440+ ft granite summit located in Chelan County of Washington state. The origin of the name came from the Sherpa Climbing Club of Ellensburg, and is inspired by the obvious resemblance to its Himalayan namesake when comparing the south faces of both. Little Annapurna is part of The Enchantments within the Alpine Lakes Wilderness, and is set on land managed by the Okanogan–Wenatchee National Forest. It belongs to the Stuart Range which is subset of the Cascade Range. Little Annapurna is situated southeast of Dragontail Peak, which is its nearest higher neighbor. Remnants of the receding Snow Creek Glacier can be found on its gentle north slope. Precipitation runoff drains into tributaries of the Wenatchee River.

The first ascent was made September 10, 1940, by Everett and Ida Zacher Darr, Joe Leuthold, and Eldon Metzger. A herd of mountain goats beneath the peak was their inspiration for so naming this geographical feature.
Le Conte Mountain is a 7,762-foot-elevation (2,366-meter) summit located on the shared boundary of Skagit County and Chelan County in Washington state. It is positioned on the crest of the North Cascades Range, and is set within the Glacier Peak Wilderness.
