The Tate Geological Museum was founded through a gift from Marion and Inez Tate in 1980. Originally called the Tate Earth Science Center and Mineralogical Museum, it changed its name in 2001 into the Tate Geological Museum since it covers earth science, mineralogy, and paleontology. Its exhibits include the Dino Den, Dee the Mammoth and the Pleistocene Exhibit, Hall of Minerals, Walk Through Time, and many more.

The Museum, which can be found within the Casper College campus, it is a great resource for the community. Numerous local school and groups come to the Museum to widen the learning experience of the students. There are very few geology and paleontology museum in Wyoming but, the Tate Geological Museum features a collection of more than 3000 fossil and mineral specimens. This makes the Museum one of the must see places during a visit to Wyoming.

The Museum offers volunteering opportunities for those who would like to take part in its various activities. Their volunteers assist in the display construction, gift shop, tours, and in the fossil preparation lab.
