Summary:
Named as a formation of Walden Creek group of Ocoee series. Named for Licklog Hollow, near edge of foothills of Great Smoky Mountain, southwest of East Fork of Little Pigeon River. Exposed only in northwest part of Walden Creek group outcrop belt. Consists of dark-gray, laminated to crudely layered, micaceous siltstone and shale. Interbedded in places with sandstone and quartz-pebble conglomerate resembling overlying Shields formation. Base is cut off by Great Smoky fault. Age is later Precambrian.

Summary:
In map area, used as Licklog formation for Walden Creek group of Ocoee series. Oldest, least extensive, and most poorly exposed unit of Walden Creek group. Well exposed where crossed by Little Pigeon River at Dunn Creek fault; elsewhere, judged only from chips in overlying soil. Overlain conformably by conglomerate of Shields formation; eastward thinning of conglomerate suggests Licklog and Shields also intertongue. Lower contact is a fault. Age is late Precambrian. Report includes geologic map, cross sections, correlation chart, and measured sections.
