We bundled up and walked from the west end to the east end, from the Ijams Homesite along the boardwalk on the River Trail to Ross Marble Quarry and the Keyhole. Along the way we passed over four sedimentary rock* formations—all Ordovician** in origin—that make up the bedrock of our 300 acres: Ottosee shale, Chapman Ridge sandstone, Holston limestone and finally to the edge of the Lenior formation of crumbly, silty limestone visible above ground as outcroppings along the old railroad track at Mead's.
