The Spray Lakes Group is a stratigraphic unit that is present on the western edge of the Western Canada Sedimentary Basin in the southern Canadian Rockies, and it comprises the Pennsylvanian-age strata of that region.[3] It was named after the Spray Lakes near Banff, Alberta,[1] and fossils of marine invertebrates are found in some of its strata.[4]
