content: Leray Chert, also known as Black River, Chaumont, or Watertown, is a dark gray (N3) chert. It is occasionally brownish gray (5YR 4/11), dull black, or shiny black. Some chert beds present, when weathered, 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. It has white spots/slivers that may be fossil shells. It has a chunky, smooth texture and is opaque. Deposits include nodules of chert that are generally flattened parallel to the plane of bedding.
