Summary:
Mapped on east side and locally on west side of Packsaddle Mountain, south of Pend Oreille Lake, Bonner Co, ID in the Idaho Mountains province. Is in contact locally on west side of mountain with the Middle Cambrian Rennie Shale. Is overlain by Quaternary deposits. Is 2,000 ft thick; top not exposed. Is poorly exposed; sequence interrupted by faulting and by intrusive rocks. Lower part of Lakeview is light- to dark-gray or black, thin-bedded, blocky to massive limestone that is locally fossiliferous and oolitic. The highest beds are light-gray to tan thin-bedded blocky, locally sandy or silty dolomite. Most of the rock is marbleized. Trilobite and brachiopod fossils found near. A new genus of brachiopod of the Pegmatretid family found in Lakeview has been known previously only from the ALBERTELLA zone of early Middle Cambrian age in eastern NV.
