Malachite Peak is a 6,261-foot (1,908-metre) mountain summit located 5.5 mi (8.9 km) south of

Mount Baker-Snoqualmie National Forest. Precipitation runoff from the mountain drains into tributaries of the Skykomish River. The nearest higher neighbor is Camp Robber Peak, 3.66 mi (5.89 km) to the south.[1] The first ascent of this peak may have been in 1937 by a team from the United States Geological Survey.[2] The USGS named the peak about 1975 based on a triangulation station marked as "Malachite".[4]

Climate

Malachite Peak is located in 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 snow onto the Cascades (Orographic lift). As a result, the west side of the Cascades experiences high precipitation, especially during the winter months in the form of snowfall. Because of maritime influence, snow tends to be wet and heavy, resulting in high avalanche danger.[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.[2]

Geology

The Alpine Lakes Wilderness features some of the most rugged topography in the

glacial valleys, and granite walls spotted with over 700 mountain lakes.[5]
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

continental lithosphere called terranes created the North Cascades about 50 million years ago.[6]

Malachite Peak from Otter Point

During the Pleistocene period dating back over two million years ago, glaciation advancing and retreating repeatedly scoured and shaped the landscape.[6] 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.[6] The U-shaped cross section of the river valleys is 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.
