Who needs Yucca Mountain, let's just use the Bingham Canyon Mine

7 Amazing Holes et al

SFW... Four mines, a glory hole, a great blue hole, and a home-eating sinkhole. 7 Amazing Holes even has a hole with a no-fly zone above it to prevent helicopters being sucked in, again. They omitted the largest meteorite crater in the world, now known as Lake El'gygytgyn. If you want depth there's the 1.4 mile deep Voronya Cave in Georgia or the 7.6 mile deep Kola Superdeep Borehole. Of course, for an virtual abyss, there's always the Black Hole of Calcutta.
