We created a rocks and minerals game that helped us learn the history of planet Earth. We learned about local, regional, and global patterns of rock formations. This activity revealed changes over time due to earth forces such as earthquakes. We looked at the hoodoo shapes in Bryce Canyon. We learned that they were formed in sedimentary rock, hoodoo shapes are affected by the erosional patterns of alternating hard and softer rock layers. The name given to the rock layer that forms hoodoos at Bryce Canyon is the Claron Formation. This layer has several rock types including siltstones and mudstones but is predominantly limestone.
