The Little Obed rises east of Crossville and from near its source flows in a deep gorge that it has cut into the rocks capping the plateau, primarily
sandstones of the PennsylvanianPeriod. The depth of the gorge seems disproportionate to the size of the stream, as is typical of many of the streams of the plateau. The erosive power of plateau streams is considerable because of the frequent and often intense rainfall in the area. The Little Obed and its gorge are bridged by U.S. Highway 127just north of Crossville; the Little Obed's confluence with the Obed Riveris slightly northwest of Crossville near the remains of a former bridge on an abandoned railroadthat once linked Nashville and Knoxville.
