If Iowa wants to get serious about doing its part to combat climate change then investments will need to be made to better understand the potential for geologic storage of CO2 in Iowa. . . . The IGS stands ready to lead this charge while collaborating with industry partners and lawmakers to make sure that Iowans do not miss the opportunity to play an integral role in securing a better climate future for our state.

The Inside Story

Tuesday, November 30, 2021
The Iowa Geological Survey (IGS) has a long and illustrious history in the state, beginning in 1855, when legislation proposed by Governor James W. Grimes provided for a geological survey of the state, which was led by State Geologist James Hall. It was the start of great things for the state of Iowa, with its many geological resources. Iowa established a permanent geological survey as a separate agency of state government in 1892

Iowa’s landscape has been reshaped throughout geologic history, most recently due to the advancement of continental ice sheets. Since the ice retreated, the landscape has undergone fluvial incision and the glacial deposits have experienced weathering and soil development.
