Luahna Peak is an 8,445-foot (2,574-metre) double summit mountain located in the Glacier Peak Wilderness of the North Cascades in Washington state. The true summit is 8,445 feet in elevation, and the northwest subpeak is 8,369 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 first ascent of the summit was made on August 13, 1911, by Rodney Glisan, H.H. Prouty, Winthrop Stone, C.W. Whittlesey, all of whom were members of the Mazamas. [2]
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. [2] Weather fronts originating in the Pacific Ocean travel northeast toward the Cascade Mountains. As fronts approach the North Cascades, they are forced upward by the peaks (orographic lift), causing them to drop their moisture in the form of rain or snow onto the Cascades. As a result, Luahna Peak experiences high precipitation, especially during the winter months in the form of snowfall which feeds its glaciers. [2] 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.
Bonanza Peak is a tall peak in the North Cascades in the U.S. state of Washington and the Glacier Peak Wilderness of the Wenatchee National Forest. At 9,516 feet (2,900 m) in elevation, it is the highest point in Chelan County, and the highest non-volcanic peak in Washington. and the Cascade Range as a whole. Bonanza Peak's prominence is 3,711 feet (1,131 m), making it the 26th most prominent peak in Washington. The nearest higher peak is Glacier Peak, 14.4 miles (23.2 km) to the southwest.
Azurite Peak is an 8,434-foot (2,571-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 ranks as the 81st-highest summit in the state. 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.

Topographic relief is significant as the summit rises over 3,000 feet above Mill Creek in one mile (1.6 km). The Pacific Crest Trail traverses the base of Azurite Peak.
Little Annapurna is an 8,485-foot (2,586-metre) mountain 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 the nearest higher neighbor.

The first ascent of the peak was made in August 1937 by Franklin Bennet, Edgar Courtwright, and Toivo Hagman. The peak's toponym refers to an abandoned copper mine that once operated at the northeast base of the peak.

The nearest higher neighbor is Bonanza Peak, 2.35 miles (3.78 km) to the west, and Riddle Peak lies 3.7 miles (6.0 km) to the east-southeast. Precipitation runoff from the mountain and meltwater from the glacier in the east cirque drains into nearby Lake Chelan via Railroad Creek and Company Creek.

Berge is positioned on Chiwawa Ridge with Buck and Napeequa, and other notable peaks on this ridge include Fortress Mountain, Brahma Peak, Cirque Mountain, Helmet Butte, and Chiwawa Mountain. Precipitation runoff from Berge drains to the headwaters of Napeequa River; or east into tributaries of the Chiwawa River.
