Summary:

Named for small creek 4 mi W of Lone Mtn [39 deg 35'21"N, 116 deg 02'29"W]. Type section is on main SW ridge leading from peak of Lone Mtn [Bartine Ranch 15' quad, Eureka Co, NV]. Is top member of 3 of McColley Canyon Formation. Mapped in Roberts Mtns, Lone Mtn, and Table Mtn. Its stratigraphic position is occupied by lower Union Mountain Formation in Sulphur Springs Range. Composed of uniform medium to thick-bedded, medium-light-gray, very fine-grained limestone. At Lone Mtn is dolomite in upper part. Is approx 180 ft thick. Underlies Denay Limestone in Roberts Mtns. and Union Mountain Formation at Table Mtn and Lone Mtn. Conformably overlies Bartine Member (new) of McColley Canyon Formation. Generally contains few identifiable fossils; however has well-preserved horn corals and Elythyna fauna. Age is Early Devonian.
