This virtual tour features three-dimensional images from the United States Geological Survey's (USGS) collection. It introduces visitors to the geology, landforms, and volcanic history of Sunset Crater National Monument, which was the scene of volcanic activity beginning in 1064 to 1065 AD and continuing for approximately 200 years. Visitors can see Sunset Cater itself, cinder and spatter cones, the ... Full description.

After a teacher led discussion (some background provided), students will break into groups and recreate global maps at four different points in earth's history. By completing this exploration activity, the learner will: recognize that continents of the western hemisphere "fit" together, create a model that demonstrates the similarity of the continents, identify the major tectonic plates, and calculate ...
