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 mapping surficial and bedrock materials, evaluating Iowa’s groundwater resources, and assisting in the search for critical minerals – all topics which have been featured in recent news and media.  In addition, the Geode showcases new mapping and monitoring activities, and even includes an article on the beautiful Loess Hills State Forest.
