A view of the stratigraphic section along the tile ditch near Glady Creek where mastodon (Mammut americanum) remains were found on the McGill farm in Concord Township, Champaign County, Ohio. The section includes marl overlain by soil overlain by gray, soil spread. The image was taken by Michael C. Hansen in September 1978. The location given is approximate to the excavation site.
The field near Glady Creek where mastodon (Mammut americanum) remains were found on the McGill farm in Concord Township, Champaign County, Ohio. Staff from the Ohio Historical Society undertook a salvage excavation at the site on September 18, 1978. An excavation trench 40 feet long, 8 feet wide, and 8 feet deep was dug in an attempt to locate additional mastodon remains. This excavation produced a first rib, the sacrum, an epiphyseal plate, skull fragments, and a toe bone. The finds were widely scattered in the excavation and appeared to have been previously disturbed, possibly by channelizing of Glady Creek in the 1930s or 1940s. The image was taken by Michael C. Hansen in September 1978. The location given is...

The Burning Tree Mastodon (Mammut americanum) excavation site at the Burning Tree Golf Course south of Heath in Licking Township, Licking County, Ohio. The Burning Tree Mastodon is one of the most complete specimens of a mastodon found to date. It was discovered on December 12, 1989, during excavation for a pond on the course. Most of the skeleton had been recovered within three days of the initial find in what was probably a peat bog formed from a small kettle lake. Five casts were made from the original specimen skeleton before it was sold to a museum in Japan. The image was taken by Michael C. Hansen on December 13, 1989. The location given is the entrance to the Burning Tree Golf Course.

The excavation site of a mastodon found on the farm belonging to Rolland Farrington north of Somerville in York Township, Union County, Ohio. The mastodon remains, shown in the peat bog, were determined to be from a juvenile animal. The mastodon (Mammut americanum) specimen was in good condition and one of the more complete mastodon specimens found in Ohio. The image was taken by Carl W. Albrecht on October 1, 1970. The location given is approximate to the excavation site.
The test trench near Glady Creek where mastodon (Mammut americanum) remains were found on the McGill farm in Concord Township, Champaign County, Ohio. Before excavation of the site began, two test trenches were dug at the north and south ends of the prospective site. The test trench depth was 5 to 7 feet. Bones were presumed to have come from the marl layers. The image was taken by Michael C. Hansen in September 1978. The location given is approximate to the excavation site.
Donn Davids, curator of natural history from the Ohio Historical Society, is pictured with some of the McGill Mastodon (Mammut americanum) bones next to a barn in Concord Township, Champaign County, Ohio. During the channelizing of Glady Creek in August 1978, some remnants of a mastodon were dredged up and deposited on an adjacent corn field. The remains were taken to the Ohio Historical Society in Columbus, Ohio, for identification. After digging test trenches in the area on September 12, 1978, staff from the Ohio Historical Society undertook a salvage excavation at the site on September 18, 1978. An excavation trench 40 feet long, 8 feet wide, and 8 feet deep was dug in an attempt to locate additional mastodon...
