It takes the name from the Stoddart Creek, a creek that flows into Charlie Lake north of Fort St. John, and was first described in well Pacific Fort St. John #23 (at depths from 2000 to 2600m) by A.T.C. Rutgers in 1958.
The Stoddart Group reaches a maximum thickness of 660 metres (2,170 ft) in the sub-surface north of Fort St. John in north-eastern British Columbia. It is present in the sub-surface from the foothills of the Northern Rockies and eastwards into the Peace River Country in north-western Alberta.

|Taylor Flat Formation||Early Pennsylvanian||limestone, dolomite, occasional sandstone, calcareous shale||152 m (500 ft)|||
|Kiskatinaw Formation||Chesterian||quartzose sandstone, dark grey shale, rare carbonate||183 m (600 ft)|||
