Le Conte Mountain is a 7,762-foot-elevation (2,366-meter)
Topographic relief is significant as the southwest aspect rises nearly 2,500 feet (760 meters) above South Cascade Lake
in less than one-half mile, and the northeast aspect rises 3,200 feet above Flat Creek in one mile.
History
This geographical feature's toponym was officially adopted by the
U.S. Board on Geographic Names to honor geologist Joseph LeConte (1823–1901).[1] The first ascent of the summit was made by Calder T. Bressler, Ralph W. Clough, Bill Cox and Tom Myers on July 23, 1938. The Southeast Ridge was first climbed in 1953 by Dale Cole, Robert Grant, Michael Hane, Erick Karlsson and Tom Miller, while the Northwest Ridge was first climbed in 1957 by Art Maki and Joe Quigley.[1]
Climate
Le Conte Mountain is located in the
Cascade Mountains. As fronts approach the North Cascades, they are forced upward by the peaks of the Cascade Range (orographic lift), causing them to drop their moisture in the form of rain or snowfall 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.[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]
Geology
The North Cascades features some of the most rugged topography in the
glacial valleys, and granite spires. 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 ago to the late
During the Pleistocene period dating back 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 area.
