This is West Virginia's New River Gorge Bridge. When you walk out onto the bridge during Bridge Day, you'll be standing over one of the oldest river gorges on Earth. By most accounts, it's the top contender for being the first river in North America. The New River Gorge in West Virginia averages between 700 and 1300 feet deep. The gorge was formed solely due to erosion; there were no glaciers in the area like those that carved our similar gorges in other parts of the world.
