Mount Logan (9,087 feet (2,770 m)) is located in North Cascades National Park in the U.S. state of Washington.[4] Mount Logan is in a remote location of North Cascades National Park that requires hiking 20 mi (32 km) from a trailhead to reach the peak. The mountain itself is not a difficult climb, though the easiest approaches require traversing glaciers and ropes are recommended.[3] The peak supports three glaciers including Banded Glacier to the north, Fremont Glacier to the southwest and Douglas Glacier on the southeast slopes.
Mount Logan is located in the marine west coast climate zone of western North America.[5] 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, causing them to drop their moisture in the form of rain or snowfall onto the Cascades (Orographic lift). As a result, the west side of the North Cascades experiences high precipitation, especially during the winter months in the form of snowfall.[5] Due to its temperate climate and proximity to the Pacific Ocean, areas west of the Cascade Crest very rarely experience temperatures below 0 °F (−18 °C) or above 80 °F (27 °C).[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] Because of maritime influence, snow tends to be wet and heavy, resulting in high avalanche danger.[5]
