Summit Chief Mountain

Mount Baker-Snoqualmie National Forest. Summit Chief Mountain is situated on the crest of the Cascade Range, nine miles northeast of Snoqualmie Pass. Precipitation runoff from the west side of the mountain drains into tributaries of the Snoqualmie River, whereas the east side drains into tributaries of the Yakima River. The nearest higher peak is Chimney Rock, 1.29 miles (2.08 km) to the southwest.^[3]

marine west coast climate zone of western North America.^[4] Weather fronts originating in the Pacific Ocean move northeast 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 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 avalanche danger.^[6] 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.^[6]

glacial valleys, and granite walls spotted with over 700 mountain lakes.^[7] 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 elevation range of this area is between about 1,000 feet (300 m) in the lower elevations to over 9,000 feet (2,700 m) on Mount Stuart

continental lithosphere called terranes created the North Cascades about 50 million years ago.^[8]
