Climbing

The

class 5.3) subpeak called "Tran Spire" (4,943 feet (1,507 m)) which was first climbed in 1958 by Don Anderson and Robert Petersen .[2][7]

Climate

Jefferson Peak is located in the

marine west coast climate zone of western North America.[8] 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.[9] 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.[9] The months April through August offer the most favorable weather for viewing or climbing this mountain.[2]

Geology

The Olympic Mountains are composed of obducted clastic wedge material and oceanic crust, primarily Eocene sandstone, turbidite, and basaltic oceanic crust.[10] The mountains were sculpted during the Pleistocene era by erosion and glaciers advancing and retreating multiple times.
