The Triassic part of this sequence has previously been inferred to be part of the Taku terrane. However, its lithology, age, fossils, and regional distribution indicate that it is probably a sliver of Wrangellia that was offset from the eastern Alaska Range to its present position by at least 350 km dextral displacement on the Denali fault.
