The Olympic National Park is home to the Olympic Mountains, a majestic range located on the Olympic Peninsula in western Washington State, USA. This mountain range is part of the Pacific Coast Ranges and is known for its diverse ecosystems, from temperate rainforests to alpine meadows. The Olympic Mountains, formed about 35 million years ago, feature Mount Olympus as their highest peak at 7,962 feet (2,428 meters). The range’s unique geography creates one of the wettest climates in the contiguous United States on its western slopes, while the eastern side experiences a rain shadow effect.
What are the Key Geographical Features of the Olympic Mountains?

The Olympic Mountains boast several distinctive geographical features:
- Elevation: The range’s highest point, Mount Olympus, stands at 7,962 feet (2,428 meters).
- Location: Bounded by the Pacific Ocean (west), Puget Sound (east), and the Strait of Juan de Fuca (north).
- Formation: Created by the collision and subduction of tectonic plates about 35 million years ago.
- Climate: Extreme precipitation on western slopes, with Mount Olympus receiving an estimated 240 inches (6,100 mm) of annual precipitation.
- Glaciers: Home to approximately 60 glaciers and numerous snowfields.
- Ecosystems: Supports diverse habitats including temperate rainforests, subalpine meadows, and mountain hemlock zones.
How was the Olympic Mountain Range Formed?

The formation of the Olympic Mountains is a fascinating geological story:
- Tectonic Activity: The range emerged due to the collision and subduction of the Juan de Fuca plate under the North American plate.
- Uplift Process: This tectonic activity uplifted and folded oceanic crust, creating the horseshoe-shaped mountain range.
- Timeframe: The formation process began approximately 35 million years ago.
- Ongoing Changes: Continued tectonic activity and erosion continue to shape the range.
