The name Kula is from a Tlingit language word meaning "all gone".[1] As the name suggests, the Kula Plate was entirely subducted around 48 Ma and today only a slab in the mantle under the Bering Sea remains.[2] There is some evidence of a Resurrection Plate broken off from the Kula Plate and also subducted.[3][4]

About 55 million years ago, the Kula Plate began an even more northerly motion. Riding on the Kula Plate was the Pacific Rim Terrane consisting of volcanic and sedimentary rock. It was scraped off and plastered against the continental margin, forming what is today Vancouver Island.
By 40 million years ago, the compressional force of the Kula Plate ceased. The existence of the Kula Plate was inferred from the westward bend in the alternating pattern of magnetic anomalies in the Pacific Plate.
