content: MRS-20 (Mississippian Reed Springs, Variety 20): MRS Variety 20. Found in Madisori Co. AR. and probably further east in adjacent counties. For a long time this was an enigmatic chert variety which no one seemed to be able to tie to a source. On the basis of morphology I suspected Reeds Spring. It was found in a worked state on many sites in Madison County,AR. Finally I found one location in a clear context just above the Pierson in the Reeds Spring. This is a green to greenish blue chert. Weathering accentuates the green color. At 10X a few silica grains glisten in bright light. Dendrites are sometimes found between fracture planes on one or both touching surfaces when broken apart. Workability is good to fine.
