A Day in the Canyon: Tilted Basalt

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.
