During most of that time, the survey has been a department of the state government. Since 2011 however, the survey has been administered by the Department of Geosciences at Western Michigan University. History First and second geological surveys On January 26, 1837, Michigan was admitted as a state.

Dr. Douglass Houghton, who created and planned the survey, convinced legislators to approve its creation and funding.
