content: Chaumont Chert is also known as Leray or Watertown. It is a dark gray (N3), occasionally brownish gray (5YR 4/11), dull black, or glossy black chert. When weathered some of the chert beds present a peculiarly fucoidal surface through intricate intermixing of the limestone with earthy films, and others are distinctly cross-stained. It also tends to be dull in color when weathered. Inclusions of white spots/slivers may be fossil shells. It has a chunky, smooth, opaque texture. Deposits include "...nodules of chert generally flattened parallel to the plane of bedding" (Johnson 1971:14).
