Dec 07, 2005 (C Papertzian) - Fossil location.
Aug 09, 2023 (Mateo Dorado-Troughton) - The upper member of the Gull River Formation in this quarry consists of grey-brown, light grey weathering, microcrystalline, thin- to medium-bedded (7-12 cm) limestone, with thin dark grey shale partings commonly separating the limestone beds. The overlying lower member of the Bobcaygeon Formation is characterized by medium grey, light grey weathering, fine- to medium- crystalline and medium- to coarse-grained calcarenitic, medium- to thick-bedded (10-50 cm) limestone. Shale partings are generally absent through this interval. The uppermost part of the section includes several massive beds, greater than 1 m thick. The formational contact is marked by a distinct limestone conglomerate in the Bobcaygeon Formation — microcrystalline lime stone clasts occur in a matrix of fine- to medium-crystal line limestone. Glacial overburden around the top of the quarry is 1 to 3 m thick. (Limestone Industries of Ontario - Vol. 2, 1998)
