Yellowstone Volcano Observatory Scientist-in-Charge Mike Poland visits Yellowstone National Park to tell the story of how the ground there moves up and down over time. This motion has been measured using a variety of techniques over the past 100 years, and from geological mapping scientists can even tell how the ground has moved going back about 15,000 years! This research indicates that the ground at Yellowstone goes up and down in cycles, some of which can last thousands of years and that are caused by accumulation and draining of fluids beneath the surface.
