In the
Titus Crow stories by
Brian Lumley, one of the sons of Cthulhu. He is, apparently, '
interred in
crypts (Why does he need multiple crypts? Eh well. He's one of the
Cthulhi, anything is possible) beneath a primal mountain, now lost in depths of ocean at the southern edge of the southeastern Pacific Plateau, about a thousand miles south of
Easter Island'.
Which would put him at, mmm, very roughly, S. 40, W. 110, if anyone fancies Cosmic Calamari for dinner.
