Image Lake
Image Lake is a tarn in Glacier Peak Wilderness, in the North Cascades of Washington, United States.〔〔 The lake is surrounded by Plummer Peak to the east, a lookout point to the west, the Miners Creek drainage and Glacier Peak to the south, and Canyon Lake to the north.〔〔〔 The course of the popular Miners Ridge Trail skirts the lake.〔〔(【引用サイトリンク】 title=Mt. Baker-Snoqualmie National Forest — Miners Ridge Trail 785 )〕 Glacier Peak can be seen from the outlet of the lake, and the peak reflected in the lake is a popular photographic subject.〔
As a result of a relatively mild temperate climate with ample precipitation, the areas around Image Lake boast rich natural habitats with many species of plants, insects, rodents, and large mammals. Native Americans took advantage of these resources, and may have inhabited the area seasonally. However, human activity such as hunting, fishing, and mining, and recreational overuse increased after the arrival of Europeans. As a result, some areas experienced significant environmental degradation near the end of the end of the nineteenth century and the early twentieth century, including the eradication of large predatory animals. Recreational overuse and the presence of livestock were especially problematic in the early to mid-twentieth century.
==Climate==
Image Lake is located in the marine west coast climate zone of western North America.〔Beckey, p. 15〕 Most weather fronts originate in the Pacific Ocean, and travel northeast toward the Cascade Mountains, which surround Image Lake. As fronts from approach the North Cascades, 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. As a result, the west side of the North Cascades experiences high precipitation, especially during the winter months in the form of snowfall.〔 Due to its temperate climate and proximity to the Pacific Ocean, areas west of the Cascade Crest very rarely experience temperatures below or above .〔 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.〔Beckey, p. 16〕 Because of maritime influence, snow tends to be wet and heavy, resulting in high avalanche danger.〔
Global warming is expected to have a number of negative long-term ecological impacts on the region, including drought, increased forest fires, forest degradation to drought and disease, and less healthy or nonexistent salmon runs. The distribution and survival of plant species, especially those that inhabit alpine environments, as well as animals that are specifically adapted to those environments, will also be adversely affected.〔 Glaciers are also expected to recede due to a decreased buildup of snowpack and higher overall temperatures.
