| Type section | |
| Named for | Kotaneelee River |
| Named by | C.O. Hage, 1945 |
It takes the name from the Kotaneelee River, and was first described in outcrop in the river valley by C.O. Hage in 1945.[2]
Lithology
The Kotaneelee Formation is composed of marine shale, sandstone, conglomerate. [1]
Distribution
The Kotaneelee Formation has a thickness of 152 metres (500 ft) to 305 metres (1,000 ft) .[1] It occurs in outcrop along the Petitot River and Liard River valleys from the Beaver River to the Kotaneelee River mouth.
Relationship to other units
The Kotaneelee Formation is gradually overlain by the Wapiti Group and conformably overlays the Dunvegan Formation.[1]
It is equivalent to the Wapiabi Formation in Alberta.

gollark: What if we make a fuzzy logic halting problem solver? Declare it non-halting if it runs for, say, 10 seconds.
gollark: O(∞) average actually.
gollark: Quickly, find some computer scientists!
gollark: Then the algorithm runs a bit slowly.
