- •
Glacial flood sediments offshore Vancouver Island originate from a Scabland Flood source.
- •
Flood layers were deposited cyclically between 19.3 and 14.9 ka.
- •
Buoyant Scabland Flood plumes traveled to the north in the Pacific Ocean.
- •
Scabland Floods lasted at least 4500 years.
- •
Paired K/Ar and εNd constitute a powerful provenance tool.
