content: PCUF-3 (Undifferentiated Felsite, Variety 3): This is a coarse textured felsite which weathers to a light tan. A medium gray field has tiny irregular spots peppered throughout. Near the cortex a lighter gray prevails. Knappability is only fair, but the variety could be worked as easily as the better grades of rhyolite. Tiny silica grains, which sparkle in the sunlight are visible at lOX. Area of availability is not known at this time. Future work will probably reveal other varieties of felsite. A search of the stream at site 23IR5 yielded a few fragments of light tan, greenish, and purplish felsite, but bedrock sources could not be found and only very small samples were collected.

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.
