We communicate about environmental stewardship and wise use of our precious natural resources through a broad understanding and appreciation for Missouri’s natural, cultural and energy resources. We invite you to read more about us and encourage you to take a self-guided tour of the Ed Clark Museum of Missouri Geology where you will find educational displays that feature rocks, minerals, fossils, and descriptions of the geologic history of Missouri, and more.
