Tilted Basalt Columns – Yakima River Canyon
This tilted basalt was the result of a plate fold being pushed up from a diagonal force. Throughout the Yakima River Canyon the basalt columns show displacement in various directions. This illustrates that forces were lateral pushing toward each other creating a “fold”.
The basalt shown here is in a “columnar” formation. Basalt formed like this cooled very slowly, creating a soother texture.
