Summary:

Immediately overlying the Mosheim Limestone Member of the Lenoir Limestone in the Cahaba Valley of AL are a few feet of distinctive light- to dark-gray coarse-grained limestone (grainstone) composed of skeletal fragments, intraclasts, peloids, and occasional ooids, referred to as the Lee Branch Member by Roberson (1988) in an unpublished University of AL M.S. thesis. The Lee Branch generally ranges from 3 to 6 ft thick, but at Shephard Branch is less than 1 ft. Age is Middle Ordovician (Whiterockian).
