Feb 24, 2017 (A Wilson) - Scattered outcrops of thin-bedded, fine- to very fine-crystalline dolostone occur in a broad region west of and northwest of the Cruickshank Owen Sound Ledgerock’s Quarry and suggest that this whole stippled area may be underlain by at least some Eramosa Member strata. This interpretation is supported by the lack of fossiliferous Guelph Formation outcrops in the area. Eramosa Member strata end abruptly at their eastern erosional edge at the Cruickshank quarry. Another area possibly underlain by Eramosa Member strata occurs south of Wiarton in a belt between Mountain Lake and Boat Lake, north of Clavering. In this belt there is an area of high potential resource which includes the McCartney Quarry and an outcrop of the interbedded unit.
