The Spray River Group is a stratigraphic unit of Triassic age. It is present on the western edge of the Western Canada Sedimentary Basin in the foothills and Rocky Mountains of western Alberta. It was originally described as the Spray River Formation by E.M. Kindle in 1924[2] and was later raised to group status.[3] Its type section is located in the Spray River gorge at the southern end of Sulphur Mountain.[3]
The Spray River Group includes marine fossils[4] from the Triassic period.[5]
