Kenneth Chert
(Photos needed)
Mottled or speckled gray and white cryptocrystalline material which outcrops in north-central Indiana along the Wabash River. Typically a darker gray on white with a speckled or mottled appearance. The chert can range from white to off-white to light gray with spots ranging from medium dark gray to almost pure black. This chert is generally chalky to earthy to porcelaneous in texture and luster. Its knappability ranges from poor to only fair. Kenneth outcrops primarily along the Wabash River in Cass and Miami Counties, Indiana, between the towns of Logansport and Peru. The main concentrations of this chert appear to be at the confluence of the Mississinewa River and the Wabash River near Peru in Miami County, Indiana. Another outcropping may occur along Wildcat Creek near Frankfort, in Clinton County, Indiana.
