Colonial Peak

7,771 ft

Colonial Peak, located in the Pacific Ranges mountain range in Washington State, is a prominent peak that attracts mountaineers and outdoor enthusiasts alike. Standing at an impressive elevation of 7,168 feet (2,185 meters), Colonial Peak offers a challenging and rewarding climbing experience.

During the winter season, the snowpack on Colonial Peak can vary significantly. The mountain receives abundant snowfall, with snowpack depths reaching several meters. This makes it an ideal destination for winter sports enthusiasts, such as backcountry skiers and snowshoers, who can enjoy the pristine snow-covered slopes.

The melting snow on Colonial Peak feeds into several creeks and rivers in the surrounding area. Notable among these is Thunder Creek, which originates from the south side of the mountain. The runoff from Colonial Peak contributes to the flow of Thunder Creek, ultimately joining the Skagit River, a key waterway in the region.

In terms of history and folklore, the name "Colonial" was given to the peak by the US Geological Survey in 1910, possibly inspired by the colonial architecture of nearby Diablo Dam. While no specific legends or lore are associated with Colonial Peak, its challenging terrain and breathtaking views continue to captivate those who venture to its summit.
