The Lynx Formation or Lynx Group is a stratigraphical unit of Dresbachian age in the Western Canadian Sedimentary Basin.
It takes the name from the Lynx Mountain, a 3,170 meters (10,400 ft) peak in the Cushina Ridge on the continental divide, and was first described on its slopes, east of Mount Robson, in the Canadian Rockies of British Columbia by C.D. Walcott in 1913.[2] It was elevated to group status by J.D. Aitken and R.G. Greggs in 1967.[3]
