Mount Johnson (Washington)

Daniel J. Evans Wilderness. At 7,680 feet (2,341 m) high, Mount Johnson is the fourth-highest peak of the Olympic Mountains, after Mount Olympus, Mount Deception, and Mount Constance.^[1] It is the highest peak in The Needles range which is a subset of the Olympic range. The nearest higher neighbor is Mount Deception, 1.34 mi (2.16 km) to the south.^[1] Mount Johnson is set in the eastern portion of the Olympic Mountains within the drainage basin of the Dungeness River. This location puts it in the rain shadow

marine west coast climate zone of western North America.^[4] Weather fronts originating in the Pacific Ocean travel northeast toward the Olympic Mountains. As fronts approach, they are forced upward by the peaks (orographic lift), causing them to drop their moisture in the form of rain or snow. As a result, the Olympics experience high precipitation, especially during the winter months in the form of snowfall.^[5] Because of maritime influence, snow tends to be wet and heavy, resulting in avalanche danger. 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] The months July through September offer the most favorable weather for viewing or climbing this peak.^[6]
