The Inside Story

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

The Boarderlands

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.

Iowa’s Vast Underground Wilderness

Who hasn’t taken a trip to a national, international, or state park, wilderness area, beach, or local fishing hole looking to come back refreshed and rejuvenated? Natural areas are vital for our health, providing cognitive and physical benefits.

Groundwater Recharge and Drought

Clearly, drought is an issue that affects all Iowans and understanding the consequences of drought on groundwater recharge will be important during an uncertain climate future.
