Craters of the Moon National Monument and Preserve is one of the premiere volcanic sites in the National Park System. It is located on the eastern Snake River Plain in Idaho and preserves the “weird and scenic landscape” of three young lava fields located along the Great Rift System. The monument cinder cones, spatter cones, young basaltic lava flows, and lava tubes.

Ebey’s Landing National Historical Reserve preserves and protects an unbroken historical record of Puget Sound exploration and settlement from the 19th century to the present. Located on Whidbey Island, the largest island in the conterminous United States, the reserve contains excellent examples of both glacial and post-glacial features and processes.

Fort Vancouver National Historic Site lies within the Portland Basin, which began forming approximately 20 million years ago due to the subduction of the Juan de Fuca Plate beneath the North American Plate. The basin’s thick layers of rock and sediment record geologic processes that include voluminous flood basalts, sedimentation, earthquakes, subsidence, and catastrophic ice age floods.
