The Snake River Plain is a long, straight feature that aligns with the recent movement of the North American Plate over the Yellowstone hot spot. As the plate moved southwestward over millions of years, the hot spot produced a chain of extinct volcanoes that now form the Snake River Plain. Therefore, this feature records the position of the hot spot over time. The other features listed may have been influenced by tectonic or other processes, but they do not record the position of the hot spot over time.
