Gething Formation is a stratigraphic unit of Lower Cretaceous (Aptian) age in the Western Canada Sedimentary Basin. It is present in northeastern British Columbia and western Alberta, and includes economically important coal deposits.
The formation is named for Gething Creek, a right tributary of the Peace River west of Hudson's Hope, and the nearby Gething Mountain. It was first described by F.H. McLearn in 1923[2] in the Peace River Canyon, an area that was partly inundated in 1968 by the Williston Lake after the construction of the W. A. C. Bennett Dam.
