The other way around. Pieces of British Columbia and Washington
state used to be connected to western Mexico. Time frame was
Middle to early Late Cretaceous. The ancestral terrane is now

terrane in Washington State are the San Juan Islands.
Strike-slip faulting similar to the San Andreas was responsible.
