The Glenogle Formation or Glenogle Shale is a stratigraphic unit of Ordovician (Arenigian to early Caradocian) age. It is present on the western edge of the Western Canada Sedimentary Basin in southeastern British Columbia.[3] It consists primarily of black shale and was named for Glenogle Creek in the Kicking Horse River area by L.D. Burling in 1923.[1][2]
The formation is known for its fossil graptolites.[1][4]
