Climate

Forbidden Peak is located in the

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.[7] Due to its temperate climate and proximity to the Pacific Ocean, areas west of the Cascade Crest very rarely experience temperatures below 0 °F (−18 °C) or above 80 °F (27 °C).[7] 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.[8] Because of maritime influence, snow tends to be wet and heavy, resulting in high avalanche danger.[8] This climate supports the Forbidden Glacier in the northwest cirque, the immense Boston Glacier to the east, and glacial remnants on the south side in Boston Basin. These glaciers carved Forbidden Peak into a classic horn
.

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 various climate differences.

The history of the formation of the Cascade Mountains dates back millions of years ago to the late

continental lithosphere called terranes created the North Cascades about 50 million years ago.[9]

During the Pleistocene period dating back over two million years ago, glaciation advancing and retreating repeatedly scoured the landscape leaving deposits of rock debris.[9] 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.
