It has promise to be at least the deepest cave in North America.
Seems to be a tossup between GES and Devil's hole. Although diving in devil's is prohibited due to the pupfish. IIRC, they lost a diver there in the 70's or 80's and his body was never recovered. The search team went to 200+ and they arrived at a deep vertical shaft. Who knows how deep it goes.
