Mist Mountain Formation
The Mist Mountain Formation is a latest Jurassic to earliest Cretaceous geologic formation in the Western Canada Sedimentary Basin of southeastern British Columbia and southwestern Alberta. It was named for outcrops along a western spur of Mist Mountain in the Canadian Rockies of Alberta. It contains economically important coal resources that are currently being mined in southeastern British Columbia.〔Gibson, D.W. 1979.

==Lithology==
The Mist Mountain Formation consists of interbedded light to dark grey siltstone, silty shale, mudstone, and sandstone, with localized occurrences of chert- and quartzite-pebble conglomerate and conglomeratic sandstone. It also contains a series of economically important coal seams.〔Glass, D.J. (editor) 1997.
