Geology of Washington
Washington State's diverse geology has been shaped by ancient volcanic eruptions, powerful earthquakes, and colossal glaciers. Over millions of years, these events have sculpted the landscape, creating the Cascade Mountain Range, Puget Sound, and the Columbia River Basalt Group.
The state's geological history dates back to the Precambrian era, over 1.5 billion years ago, when the North American continent began to form. During the Mesozoic era, around 200 million years ago, the forces of tectonic plate movement caused the formation of the Cascade Range, which is still active today with volcanoes like Mount St. Helens, Mount Rainier, and Mount Baker.
Washington's Ice Age history is characterized by the Cordilleran Ice Sheet, which covered much of the state about 15,000 years ago. The retreat of the ice sheet led to the formation of the Puget Sound, a complex system of interconnected marine waterways. Meanwhile, massive floods, known as the Missoula Floods, carved out the Channeled Scablands and shaped the Columbia River Gorge.
The state is also known for its rich fossil history, with sites like the Stonerose Interpretive Center in Republic offering glimpses into the Eocene epoch, approximately 50 million years ago. Here, visitors can find well-preserved plant and insect fossils, providing a window into Washington's lush, subtropical past.
Washington's diverse geological history has produced a treasure trove of rocks, minerals, and fossils for rockhounding enthusiasts to explore, offering a captivating look into the state's ancient past.
