List Description

This list shows all peaks in Washington State that are high points of primary drainage basins with an area of over 200 square miles. A primary basin is that of a river that reaches the sea, so high points of basins of tributary rivers are excluded.

Over half of Washington is part of the vast Columbia River Basin, but the well-watered western part of the state has a healthy collection of smaller rivers that drain the Olympic Peninsula and the western slopes of the Cascades. Many of these high points are well-known peaks that many Washington climbers normally ascend in the course of their careers, so it is likely that many peakbaggers already have a head-start on this list even if they are seeing it for the first time.
