It is part of the [North Cascades](/source/North_Cascades) Range and is situated one mile south of [Cascade Pass](/source/Cascade_Pass) on the shared border of [North Cascades National Park](/source/North_Cascades_National_Park) and [Glacier Peak Wilderness](/source/Glacier_Peak_Wilderness). The nearest higher peak is [Magic Mountain](/source/Magic_Mountain_(Washington)), {{convert|1.02|mi|km}} to the east-southeast. Mix-up Peak is at the northern end of the [Ptarmigan Traverse](/source/Ptarmigan_Traverse) which is an alpine route to remote mountains such as [Mount Formidable](/source/Mount_Formidable) and [Dome Peak](/source/Dome_Peak). The [Cache Glacier](/source/Cache_Col_Glacier) occupies a cirque below its eastern flank. [Surface runoff](/source/Surface_runoff) on the east side the mountain drains into the [Stehekin River](/source/Stehekin_River), whereas precipitation runoff drains into the [Cascade River](/source/Cascade_River_(Washington)) from the west side. ==Climate== Mix-up Peak is located in the [marine west coast](/source/marine_west_coast) climate zone of western North America.Beckey, Fred W. Cascade Alpine Guide, Climbing and High Routes. Seattle, WA: Mountaineers Books, 2008. Most [weather front](/source/weather_front)s coming off the Pacific Ocean travel northeast toward the [Cascade Mountains](/source/Cascade_Mountains). As fronts approach the North Cascades, they are forced upward by the peaks of the Cascade Range ([orographic lift](/source/orographic_lift)), causing them to drop their moisture in the form of rain or snow 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. Because of [maritime influence](/source/Oceanic_climate), snow tends to be wet and heavy, resulting in high [avalanche](/source/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.Beckey, p. 16 ==Geology== The North Cascades features some of the most rugged topography in the [Cascade Range](/source/Cascade_Range) with craggy peaks and ridges and deep [glacial valley](/source/glacial_valley)s. 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 [ecoregion](/source/ecoregion)s in this area. The history of the formation of the Cascade Mountains dates back millions of years ago to the late [Eocene](/source/Eocene) Epoch.{{cite book|last=Kruckeberg|first=Arthur|title=The Natural History of Puget Sound Country|publisher=University of Washington Press|year=1991}} With the [North American Plate](/source/North_American_Plate) overriding the [Pacific Plate](/source/Pacific_Plate), episodes of [volcanic igneous activity](/source/volcano) persisted. In addition, small fragments of the [oceanic](/source/oceanic_lithosphere) and [continental lithosphere](/source/continental_lithosphere) called [terrane](/source/terrane)s created the [North Cascades](/source/North_Cascades) about 50 million years ago. During the [Pleistocene](/source/Pleistocene) period dating back over two million years ago, glaciation advancing and retreating repeatedly scoured the landscape leaving deposits of rock debris. The U-shaped cross section of the river valleys is a result of recent glaciation. [Uplift](/source/orogeny) and [fault](/source/fault_(geology))ing in combination with glaciation have been the dominant processes which have created the tall peaks and deep valleys of the North Cascades area. ==Gallery== File:Mix-up Peak in winter.jpg|Mix-up Peak in winter File:Mix-up Peak from Sahale Arm.jpg|Mix-up Peak from Sahale Arm ==See also== {{Portal|Mountains}} * [Geography of Washington (state)](/source/Geography_of_Washington_(state)) * [Geology of the Pacific Northwest](/source/Geology_of_the_Pacific_Northwest) ==References== {{reflist}} ==External links== {{commons}} *[https://www.nps.gov/noca/index.htm North Cascades National Park] National Park Service * Mix-up Peak weather: [https://www.mountain-forecast.com/peaks/Mix-up-Peak/forecasts/2204 Mountain Forecast] Category:North Cascades of Washington (state) Category:Mountains of Chelan County, Washington Category:Mountains of Skagit County, Washington Category:North Cascades National Park Category:Two-thousanders of the United States --- Adapted from the Wikipedia article [Mix-up Peak](https://en.wikipedia.org/wiki/Mix-up_Peak) by Wikipedia contributors ([contributor history](https://en.wikipedia.org/wiki/Mix-up_Peak?action=history)).
