  1. The area around the bridge is quite interesting geologically. There is an old volcano to the southwest and the basalt from the vent makes up the cliffs on the west side of the bridge. At one point, a few million years ago (I can check the actual age), the top of the flows were level with the surrounding terrain. It is a good example of how much erosion and uplift has taken place since that time.
