Celebrating 160 years of service to Missourians
One hundred sixty years is not a very long time when speaking in geologic terms. However, the Missouri Department of Natural Resources' Geological Survey is observing this noteworthy milestone this year. Since 1853, the Missouri Geological Survey has provided reliable scientific information to describe and understand Missouri's wealth of natural resources.
Plan to visit our Edward L. Clark Museum of Missouri Geology this year to learn about the geology of Missouri and about contributions staff members have made to both the environmental and economic vitality of Missouri. Read more.
Sinkholes are depressed or collapsed areas formed by dissolution of carbonate bedrock or collapse of underlying caves. They range in size from several square yards to hundreds of acres and may be very shallow or hundreds of feet deep. Sinkholes are part of what is called “karst” topography, which also includes caves, spring and losing streams. We provide assistance to the citizens of Missouri by evaluating the causes and impacts of sinkhole formation and collapse. Geologists perform geologic and hydrologic evaluation to determine if collapse is attributed to a natural karst feature or is associated with the failure of a man-made feature. Learn more.
