Fault striae, Alaska

This image is of a fault surface on the road to Valdez in Alaska. Features to note and trace here include: 1) fault striae directions, and 2) a joint set. There are some additional features that can be seen here if you use what you have learned looking at other fault surfaces.

The main question that can be raised here is what is the significance of the different striae directions.
