Cascadia Channel information


Cascadia Channel is the most extensive deep-sea channel currently known (as of 1969) of the Pacific Ocean. It extends across Cascadia Abyssal Plain, through the Blanco Fracture Zone, and into Tufts Abyssal Plain.[1] Notably, Cascadia Channel has tributaries, akin to river tributaries.[2]

Cascadia Channel has two contributing tributaries—Juan de Fuca Channel from the north, and the outflow of Quinault and Willapa Channels in the south.[2] The channel is believed to be over 2,200 kilometres (1,400 mi) long.[1]
