Basalt Formations and Soda Spring at Cascadia State Park

The impressive basalt formations at Cascadia State Park are part of the Columbia River Basalt Group, one of the Earth's youngest and best-preserved continental flood basalt provinces. These vast basalt flows occurred between 17 and 14 million years ago. As the molten rock cooled, it fractured into distinct polygonal columns, a process known as columnar jointing, forming the dramatic cliffs seen today, particularly at Lower Soda Creek Falls.

The historic Soda Spring at Cascadia State Park, once renowned for its "healing mineral waters" and the site of a former health resort, is still present next to Soda Creek. However, it is no longer functional as a public drinking source. While the fountain remains, visitors should not attempt to drink the water.
