Holes
Points and comments are a snapshot, not live.
XKCD's 'Holes' visualizes the depths of notable holes on a logarithmic scale.
The comic shows cross-sections of various holes, from hand-dug wells and mines to the Kola Superdeep Borehole and Deepwater Horizon, comparing their depths on a logarithmic scale. Hover text highlights the Cave of the Crystals in Mexico.
What commenters are saying
Commenters shared examples and details about holes in the comic, including the Pantai Remis mine collapse, Lake Peigneur whirlpool, and Lake Baikal's sediment depth. Some debated whether the deepest holes stopping near 12km was a coincidence. Explain XKCD was briefly hugged to death. One commenter noted the misspelling of 'Derinkuyu'.
