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
