Porters Pinnacles
Porters Pinnacles is a group of low ice-covered rocks forming a menace to navigation along the north coast of Thurston Island, located about 4 nautical miles (7 km) north of the east extremity of Glacier Bight. Discovered by the U.S. Navy Bellingshausen Sea Expedition in February 1960, and named for Commander Philip W. Porter, Jr., U.S. Navy, commander of the icebreaker USS Glacier which made this discovery.

gollark: Does gcd.hs work then, somehow?
gollark: That's suspiciously simple then, hm.
gollark: What's `findRem` doing? Doesn't Haskell have a mod function?
gollark: It's going to have a fun feature where if it detects that you're running it *while* the uninstaller is open, it will subtly mess up your answers.
gollark: After realizing I had absolutely no idea how the "general number field sieve" and such worked, I just decided to implement Pollard's ρ one, but it requires gcd which Lua doesn't have, so I'm looking up the Euclidean algorithm.
