Field Trip: Cambrian and Ordovician Stratigraphy of Southwestern Wisconsin
Field trip route and notes looking at Cambrian and Middle Ordovician rocks of southwestern Wisconsin. -
2017 Year in Review
In 2017, Survey staff worked in 69 Wisconsin counties. We mapped geology, inventoried springs, and created groundwater models. We provide natural resource managers – land and water conservationists, county boards, and water utilities – with the information they need to protect and share their resources. This publication provides a summary of some of the... -
