Yellowstone National Park is home to a supervolcano, a volcano capable of ejecting more than 1,000 cubic kilometers (240 cubic miles) of material.The Yellowstone supervolcano last erupted about 640,000 years ago. When it did, it left behind a caldera, a landform created by the inward collapse of a volcano's peak.This simple map outlines the extent of the Yellowstone Caldera, as well as some basic physical features of the region. Study the map and the scale bar (which provides information on relative distance) to answer the questions in the "Questions" tab.Instructional IdeasConsult National Geography Standard 1.4 (4th grade): How to use maps and other geographic representations, geospatial technologies, and spatial thinking to understand and communicate information.

Methods might include:• a review of DOGSTAILS, or the elements of a good map, discussed in “Extending the Learning” in our activity “Important Places.”• the use of color in maps• identifying geographic features, such as lakes and mountains, in maps• estimating distance using a map's scale bar
