content: PCUF-2 (Undifferentiated Felsite, Variety 2): A light gray to blue-gray ground sometimes features irregular darker splotches. Some samples also feature small rounded light gray areas or spots with dark gray centers. These features are of a coarser texture than the surrounding matrix inmost instances. Cortex weathers to a light tan or gray and often has a light purplish patina in places. Also one frequently notices light or darker streaks and spots, and a few selections feature zones of light and dark bands on the weathered surface only. Texture is often fairly fine, although some approaches medium. This variety often superficially resembles some Reeds Springs cherts. Area of availability is not known at this time.

content: FELSITE. Several formations in the area produce felsite. In most cases the texture of felsite is finer, often approaching that of the better grades of chert. It could easily be confused with some of the Reeds Spring and Pierson cherts if one is not careful. I took samples from three different localities, so other varieties may well exist. Undifferentiated Felsite: In situ and stream transported felsite was discovered in a creekbed several miles south of Ironton. None of the geological maps available to the writer labeled this felsite deposit. Most of the specimens loose in the creek bed were the same as the in situ bedrock.
