Английская Википедия:Goat Mountain (Whatcom County)
Goat Mountain is a 6,844 ft summit in the Skagit Range which is a subset of the North Cascades of Washington state.[1] It is located south of Mount Larrabee and north of Mount Shuksan in the Mount Baker Wilderness, which is managed by the Mount Baker-Snoqualmie National Forest. Goat Mountain has a subsidiary 6,725 ft summit known as the west peak, and remnants of what was colloquially known as the Swamp Creek Glacier rest on the northern slope between the two summits. Its nearest higher neighbor is Mount Chardonnay, Шаблон:Convert to the east.[2] The Silver Tip Mine was located on the south slope of the mountain near the 3,000 ft level. The mine produced silver and gold in the 1940s.[3] Precipitation runoff from the mountain drains into tributaries of the Fraser River and the Nooksack River.
Climate
Goat Mountain 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 (Orographic lift), causing them to drop their moisture in the form of rain or 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.[4] Because of maritime influence, snow tends to be wet and heavy, resulting in high avalanche danger.[4] Due to its temperate climate and proximity to the Pacific Ocean, areas west of the Cascade Crest very rarely experience temperatures below Шаблон:Convert or above Шаблон:Convert.[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.[4] The months July through September offer the most favorable weather for viewing or climbing this peak.
Geology
The North Cascades features some of the most rugged topography in the Cascade Range with craggy peaks, 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 the various climate differences.
The history of the formation of the Cascade Mountains dates back millions of years ago to the late Eocene Epoch.[5] With the North American Plate overriding the Pacific Plate, episodes of volcanic igneous activity persisted.[5] In addition, small fragments of the oceanic and continental lithosphere called terranes created the North Cascades about 50 million years ago.[5] The rock of Goat Mountain is Darrington Phyllite of the Easton terrane.
During the Pleistocene period dating back over two million years ago, glaciation advancing and retreating repeatedly scoured the landscape leaving deposits of rock debris.[5] 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.
