Three Wives is a 7,450 foot (2,271 m) mountain summit located in North Cascades National Park, in Chelan County of Washington state, USA. It is situated in the Methow Mountains, a subset of the North Cascades. Neighbors include Hock Mountain 3 miles (4.8 km) to the east-northeast and Bowen Mountain, the nearest higher neighbor, 2 miles (3.2 km) to the south.[1] Precipitation runoff from Three Wives drains into tributaries of Bridge Creek, which in turn is a tributary of the Stehekin River. The first ascent of the summit was made by John Roper on October 10, 1980.[3] The mountain's name was applied by Roper, but has not been officially adopted by the United States Board on Geographic Names, so it does not appear on USGS maps.

Climate

Cascade Mountains. As fronts approach the North Cascades, they are forced upward (Orographic lift) by the peaks of the Cascade Range, 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, 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.[4]

Geology

The North Cascades has some of the most rugged topography in the

glacial valleys. 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 history of the formation of the Cascade Mountains dates back millions of years to the late

continental lithosphere called terranes created the North Cascades about 50 million years ago.[5]

During the Pleistocene period, over two million years ago, glaciation advancing and retreating repeatedly scoured the landscape leaving deposits of rock debris.[5] The U-shaped cross section of the river valleys is a result of recent glaciation. Uplift and faulting in combination with glaciation have been the dominant processes which have created the tall peaks and deep valleys of the North Cascades.
