Summary:
Named the Ottosee shale of the Blount group for Ottosee Lake, Chilhowee Park, Knoxville, TN. Consists of mainly shales and thin limestones; in one area it includes an 80 foot thick massive pink marble bed. Unit is 35 to 1200 feet thick. It unconformably overlies the Holston marble in the Knoxville trough and the Tellico sandstone in the Athens trough, and underlies the Lowville formation. The Ottosee is considered the top formation in the Blount group and is of Early Ordovician age.

Summary:
The Ottosee Shale is included in the Chickamauga Group in TN. Consists of fossiliferous shale, siltstone, sandstone, and marble. Shales are brown, brownish-gray, and medium- to dark-gray, and weather yellowish-gray or yellowish-brown. Limestones are coarse and argillaceous. Pinkish marble, similar to the Holston Formation, is scattered throughout the formation. Thickness ranges from 700 to 2000 feet. The Ottosee is of Middle Ordovician age.
