Karst geology and groundwater quality event in Prairie du Chien

PRAIRIE DU CHIEN - Crawford Stewardship Project and Valley Stewardship Network continue their series of karst citizen science events with an upcoming pizza party on Friday, Nov. 3, 7 to 9 p.m. at the Prairie du Chien City Hall. 

Community members are invited to participate in an educational and engaging citizen science effort to identify sinkholes that will be used to help develop a long overdue geological survey of Crawford County.

Karst Landscapes & Groundwater Susceptibility - A Survey of Crawford County will be a useful tool for landowners, local government, and agricultural agencies for identifying appropriate land use practices to protect groundwater. This tool is also crucial to citizens who want to ensure safe and clean drinking water. 

The event is free and open to the public.  Participants will also take part in a pizza party with pizza donations from Muddy Waters Pizza, a new restaurant in downtown Prairie du Chien.  Crawford Stewardship Project will be providing beverages.

We will meet at the Prairie du Chien City Hall at 7 p.m. to begin verifying sinkholes through our user-friendly web-platform via aerial imagery. Laptop owners are highly encouraged to bring their own computers!

Much useful data for this tool has been achieved in our last three events with guidance from our Legion GIS (Geographic Information Systems) professionals, Professor Emeritus Kelvin Rodolfo, and many volunteer citizen-scientists just like you!  All are welcome to help continue the good work!
