Fisher Peak is an 8,087-foot-elevation (2,465-meter) mountain
Topographic relief is significant as the east aspect rises approximately 2,100 feet (640 meters) in less than one-half mile (0.8 km). The mountain's toponym has been officially adopted by the United States Board on Geographic Names.[3]
Climate
Fisher Peak is located in the
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. Because of maritime influence, snow tends to be wet and heavy, resulting in high avalanche danger.[5] 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.[5]
Geology
The North Cascades features some of the most rugged topography in the
glacial valleys. Geological events occurring many years ago created the diverse topography and drastic elevation changes over the Cascade Range leading to the various climate differences. These climate differences lead to vegetation variety defining the ecoregions
in this area.
The history of the formation of the Cascade Mountains dates back millions of years ago to the late
During the Pleistocene period dating back over two million years ago, glaciation advancing and retreating repeatedly scoured the landscape leaving deposits of rock debris.[6] 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.
