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. It consists primarily of black shale and was named for Glenogle Creek in the Kicking Horse River area by L.D. Burling in 1923.
The formation is known for its fossil graptolites.
