Missouri Department of Natural Resources -- Celebrating 40 YearsCelebrating 40 years of taking care of Missouri's natural resources

This year marks the Missouri Department of Natural Resources' 40th anniversary of taking care of Missouri's natural resources.

Thanks to the hard work and dedication of many, we have made significant improvements to our state's air, land and water quality. With your help, we've been able to help improve Missouri's natural resources and public health giving us all great reason to pause and celebrate a successful 40th anniversary.

We will continue to work together to provide all Missourians a healthy environment in which to live, work and enjoy the outdoors. Learn more and be sure to enter our photo contest.


Calling all Missouri K-9 Teachers

MMEF Workshop

K-9 teachers, mark your calendars for July 13-18, 2014. The Missouri Minerals Education Foundation invites you to participate in the 14th annual "Missouri is a State of Mines - Rocks, Minerals and Our Environment" workshop to be held at William Jewell College, Liberty, Missouri. This FREE workshop provides information, ideas, materials and classroom activities involving geology, minerals, mining, and the wise use of our natural resources which participants can begin immediately using in the classroom.

Registration forms and more information can be found on MMEF's website.

The Missouri Geological Survey has a long history partnering with the Missouri Minerals Education Foundation to provide educational experiences for teachers during the foundation's workshop. Geologists with the Survey will lead sessions during this year's workshop.


GeoSTRAT – Geosciences Technical Resource Assessment Tool

GeoSTRAT Find 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 in Missouri 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.
