This is a digital elevation model of Grand Teton National Park and Yellowstone National Park. This DEM shows terrain relief and is a representation of continuous elevation values by a set of z-values and referenced to a common datum. The map also shows elevation change represented by the change in colors from GPS receivers and satellites. According to research from the University of Utah, Yellowstone's "supervolcano" is rising and is shown by the red arrows pointing upwards which shows the rise in the Yellowstone caldera.
