Grasshopper Peak

Grasshopper Peak is located near the southern end of the White Mountains which are a small subrange of the North Cascades.^[4] It is set along the boundary of Glacier Peak Wilderness on land administered by the Okanogan–Wenatchee National Forest.^[2] Precipitation runoff from the mountain's west slope drains into the White River, whereas the east slope drains into the Napeequa River. Topographic relief is significant as the summit rises 4,800 feet (1,500 meters) above the White River in 1.35 mile (2.17 km) and 4,320 feet (1,320 meters) above the Napeequa in 0.9 mile (1.45 km). This mountain's toponym has not been officially adopted by the United States Board on Geographic Names, so it is not labelled on USGS maps, and will remain unofficial as long as the USGS policy of not adopting new toponyms in designated wilderness areas remains in effect.

Grasshopper Peak is located in the marine west coast climate zone of western North America.^[1] Most weather fronts originate in the Pacific Ocean and travel east 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.^[1] Because of maritime influence, snow tends to be wet and heavy, resulting in high avalanche danger.^[1] 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.^[1] The months July through September offer the most favorable weather for viewing or climbing this peak.
