Chinook Peak

Chinook Peak is a mountain summit located on the eastern border of Mount Rainier National Park in Washington. The peak rises prominently from the surrounding ridge and serves as a natural watershed divide between two major river systems in the region.

The peak marks a county boundary that became established when Mount Rainier National Park was created. This geographical division has influenced how the surrounding mountain landscape has been managed and protected.

The summit serves as a natural marker for weather pattern changes, with its visibility from multiple vantage points making it a reference point for local communities.

The peak is most accessible during warmer months when snow coverage is reduced. Visitors should prepare for steep terrain and exposed conditions that require mountain climbing experience.

The peak receives heavy wet snowfall during winter months due to maritime weather influences. This type of snow creates distinct climbing challenges compared to the drier conditions found on other peaks in the range.
