The 2023 annual Indiana Geological and Water Survey calendar, Giants Underfoot, is now available for in-store purchase. The American mastodon (Mammut americanum) was one of the most abundant Ice Age mammals in what is now the Midwest. Mastodon fossils have been found in every county in Indiana. Only in 2022, though, did the mastodon become Indiana's state fossil–approximately 10,000 years after mastodons went extinct. The 21- by 33-inch calendar is printed in full color on heavy poster paper. NOTE: Available for in-store purchase only at this time.
