Schooler Creek Group

The Schooler Creek Group is a stratigraphic unit of Middle to Late Triassic (Ladinian to Norian) age in the Western Canadian Sedimentary Basin. It is present in northeastern British Columbia. It was named for Schooler Creek, a left tributary of Williston Lake, and was first described in two oil wells (Pacific Fort St. John No. 16 and Southern Production No. B-14-1) northwest of Fort St. John, by F.H. McLearn in 1921. Exposures along Williston Lake serve as a type locality in outcrop.
Lithology.
The Schooler Creek Group is composed of limestone and dolomite, with subordinate siltstone, shale, sandstone, and evaporite minerals such as gypsum and anhydrite.
Distribution.
The Schooler Creek Group outcrops in the foothills of the northern Canadian Rockies in northeastern British Columbia, where it reaches its maximum thickness of . In the subsurface, it extends throughout the plains of the Peace River Country. The Pardonet Formation has its type locality at Pardonet Hill, on the south shore of the Williston Lake at .
