Created in 1853, the Missouri Geological Survey (MGS) serves the citizens of Missouri by providing systematic geoscience information to support stewardship of water, land and mineral resources. MGS interprets the state’s geological setting and the availability of its energy and mineral resources for economic development in an environmentally safe manner; assuring mined land is returned to the best possible condition for use after mining is completed. MGS produces geologic maps and provides technical assistance to the citizens of Missouri by evaluating the causes and repercussions of earthquakes, landslide development and sinkhole and mine collapse. Staff ascertain that new water wells are constructed to minimum standards as set by the state regulations. This helps ensure our groundwater resources are protected from contamination due to poor well construction or abandonment of wells. Staff members provide technical oversight for many geologic investigations and issues in the state and is the authority for water quantity issues such as statewide water use and availability, water resources monitoring and planning, drought assessment, flood and hydrology studies, wetland studies and dam and reservoir safety. MGS works closely with university, government, industry and community partners to ensure response to the diverse needs of Missouri.


Visit our Ed Clark Museum of Missouri Geology June 20-24 and learn about the state dinosaur while participating in The Centre's Selfie Contest

The Centre's Selfie Contest | Ed Clark Museum of Missouri Geology

Visit the museum during the hours of 8 a.m. to 5 p.m., June 20-24 to participate. Read about the contest, rules and more online on the The Centre's Selfie Contest page. You could win a minature dinosaur model, a Geologic Map of Missouri, a polished piece of Mozarkite, Geologic Wonders and Curiosities of Missouri, a set of Natural Resources Educational Trading Cards, a Missouri Rock and Mineral Set, a Missouri Geological Survey Hat (this style, but red and grey), and more from other participating sites. Also, stop by the Missouri Geology Store after you visit the museum and check out the things that are available.


Geologist's Field Notebooks

Field NotebooksMuch like the celebrated journals from Lewis and Clark’s Expedition in early 19th century America, geologists with the Department of Natural Resources’ Missouri Geological Survey have been keeping journals since the mid-1800s. Thanks to a cooperative effort with the U.S. Geological Survey’s National Geological and Geophysical Data Preservation Program and the department, these journals known as “Geologist’s field notebooks” are being preserved and will be made available online as PDFs. Some are available now by request. Learn more.

 

 


GeoSTRAT – Geosciences Technical Resource Assessment Tool

NASCIO Recognizes Outstanding Achievements in State IT: Finalists Announced for 2015 NASCIO State IT Recognition AwardsFind locations of springs, mines, sinkholes and more using the Missouri Geosciences Technical Resource Assessment Tool.  GeoSTRAT is a Web application that makes geologic and hydrologic data readily available for public use.  GeoSTRAT enables users to easily visualize and explore geospatial data using an interactive map.  Data also can be downloaded in formats compatible with a variety of free and commercial mapping software.  GeoSTRAT can be used in the office or in the field.

Sinkhole Collapse

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.
