|Schooler Creek Group
Stratigraphic range: Ladinian to Norian
|Sub-units||Bocock Formation, Pardonet Formation, Baldonnel Formation, Ludington Formation, Charlie Lake Formation, Halfway Formation|
|Underlies||Fernie, Bullhead, Fort St. John Group|
|Overlies||Toad Formation, Doig Formation|
|Thickness||up to 730 feet (220 m)|
|Other||Siltstone, shale, evaporite|
|Region||Alberta, British Columbia|
|Named by||F.H. McLearn, 1921|
It was named for Schooler Creek, a left tributary of the Williston Lake, and was first described north-west of Fort St. John in the Pacific Fort St. John No. 16 and Southern Production No. B-14-1 wells by F.H. McLearn in 1921.
The Schooler Creek Group occurs in outcrops in the Canadian Rockies foothills, and a surface type locality for part of the Group can be found along Williston Lake. In the sub-surface it extends east and north from the Liard River throughout the Peace River Country. It reaches a maximum thickness of 730 feet (220 m) in the foothills.
