I think that would be more along the lines of Dagon. I think Cthulhu is pretty much reserved to the depths of space.
Nope, Father Dagon is east coast - his boys rule the north Atlantic.
Great Cthulhu sleeps in R'lyeh in the Pacific, dead and dreaming for when the Old Ones return.
Yog'Sothoth is in between, the Gate and Key, neither here nor there, but everywhere.
Hastur dwells in ruined Carcosa on Aldeberan, his Byahkhee able to bring you across the empty void.
The Mi'Go dwell on dark Yuggoth (Also known as Pluto - man are they pissed bout that planetary downgrade).
Azathoth, the beginning and the end, the form and formless sits in the center of the Universe, awaiting the sign to Devour all creation once again.
Ooops, I thnk I've revealed my Inner Lovercraft Geek...
