Sherpa Peak is an 8,605-foot (2,623-metre) granite summit located in the Stuart Range, in the Alpine Lakes Wilderness in Chelan County of Washington state. According to the USGS, this peak is "named for a local climbing club" that was "active in the area since the 1950s." In the 1953, a Tibetan-born Sherpa named Tenzing Norgay was the first to summit Mt. Everest with Sir Edmund Hillary. The nearest higher peak is Mount Stuart, 0.41 mi (0.66 km) to the west, and Argonaut Peak lies 1.29 mi (2.08 km) to the east. The Sherpa Glacier lies on the northern slope of the peak. Precipitation runoff from the peak drains north into Mountaineer Creek, a tributary of Icicle Creek, or south into Ingalls Creek, all of which winds up in the Wenatchee River.
Climate
Most weather fronts originate in the Pacific Ocean, and travel east toward the Cascade Mountains. As fronts approach, 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, the Cascades experience high precipitation, especially during the winter months in the form of snowfall. 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.
Geology
The Alpine Lakes Wilderness features some of the most rugged topography in the Cascade Range with craggy peaks and ridges, deep glacial valleys, and granite walls spotted with over 700 mountain lakes. 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 history of the formation of the Cascade Mountains dates back millions of years ago to the late Eocene Epoch. With the North American Plate overriding the Pacific Plate, episodes of volcanic igneous activity persisted. In addition, small fragments of the oceanic and continental lithosphere called terranes created the North Cascades about 50 million years ago. Sherpa Peak is situated in part of the Mount Stuart batholith, a large area of clean granite rock that forms the Stuart Range.
During the Pleistocene period dating back over two million years ago, glaciation advancing and retreating repeatedly scoured the landscape leaving deposits of rock debris. The last glacial retreat in the Alpine Lakes area began about 14,000 years ago and was north of the Canada–US border by 10,000 years ago. The “U”-shaped cross section of the river valleys are a result of that 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 Alpine Lakes Wilderness area.
