| Title | Odanah Member of the Pierre Formation, North Dakota |
|---|---|
| Description | The Odanah Member is exposed in a shale pit on the north side of the road. The unit was deposited in a shallow-water marine environment during the Cretaceous about 71 to 74 million years ago (interpreted from Hardenbol et al., 1998). The Odanah Member is a hard, siliceous, light-gray shale and forms conspicuous cliffs. It is locally quarried for road-surfacing material. Fossils are scarce in the Odanah, although oyster and inoceramid fossils have been recovered. |
