Physical Features of Washington

Washington features a diverse landscape that includes rugged coastlines, mountain ranges, forests, and dry interior plains. The Cascade Range divides the state into two distinct regions, with wet, forested areas to the west and arid plains to the east. The Olympic Mountains rise in the northwest, while the Columbia Plateau dominates eastern Washington. The Pacific Ocean borders the west, and major rivers like the Columbia shape valleys and provide important waterways across the state.
