The Gething bentonite occurrence lies above the south fork of Gething Creek, 6 kilometres west of Portage Mountain and 90 kilometres northeast of the town of Mackenzie, in the Liard Mining Division.

The Gething showing is located near the eastern extent of deformation in the fold and thrust belt that characterizes the Rocky Mountain Front. The region is underlain by dominantly Jurassic to Cretaceous sedimentary rocks of Ancestral North American tectonic provenance.

A 10-centimetre seam of bentonite, near the base of a measured section of several hundred metres of Lower Cretaceous Moosebar Formation (Fort St. John Group) shale and sandstone, was reported in Geological Survey of Canada Paper 44-19. A detailed description was not given.
