content: L-1436 (Chaumont Chert): The limestone and chert is plainly exposed on the south side of the Black River. Irregular chert nodules are extremely difficult to remove. Best approach is to pry chunks of the matrix loose and retrieve from them.

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).
