I guess there are some caves or tunnels near St Paul — historically, the city was originally named Pig’s Eye, after a brewer/tavern keeper who owned a cave near the Mississippi, so it’s not surprising there are caves connected to the river. These actually look like old sewer lines, too.
Anyway, some people explore these places. (Note: there is no information in the soundtrack, it’s just noise, so you can turn it off and miss nothing).
Now I’m wondering, if someone rediscovers these caves in 50-100 thousand years, how will they interpret the cave art?
