Please enjoy an online copy of our magazine, The IGS Geode, showcasing some of the Iowa Geological Survey’s activities during the past year.  This year we are highlighting projects related to carbon sequestration, sinkhole locations and karst susceptibility and groundwater resources. The Geode also showcases new mapping initiatives, monitoring activities and even includes an article on the beautiful Ledges State Park.
