Here's a more detailed map of the Juan de Fuca plate showing the age of oceanic crust on either side of the spreading ridge. Note oceanic crust west of the ridge is > 15 million years; whereas, between the spreading ridge and the Cascadia subduction zone, oceanic crust is < 8 million years.

1.5 miles deep in a black smoker on the Juan de Fuca Ridge off Washington lives an extremophile microbe (archaean) that thrives at 250 degrees F and can survive 266 degrees.
