History

The Saddle Mountains near Mattawa, Washington, are a rugged basalt ridge formed by ancient volcanic activity and shaped over millions of years by erosion and Ice Age floods. Part of the Columbia River Basalt Group, the mountains were created by massive lava flows around 15 million years ago. During the last Ice Age, cataclysmic floods from Glacial Lake Missoula carved deep channels and exposed layers of rock, leaving behind the dramatic landscapes seen today. The region is also rich in petrified wood, remnants of ancient forests that thrived here before being buried and fossilized by volcanic ash. Historically, the area was inhabited by Native American tribes, including the Wanapum, who lived along the Columbia River and relied on its resources for fishing, hunting, and trade. In the 20th century, the region became known for agriculture and hydroelectric projects, with the nearby Columbia River providing irrigation and power. Today, the Saddle Mountains remain a popular destination for off-roading, rockhounding, and exploring the unique geological history of central Washington.
