I love geographic puzzles such as this one. Here are links to some other interesting ones.

Longest straight lines of sight, modulo some atmospheric refraction (has been discussed on HN before): https://beyondhorizons.eu/lines-of-sight/

Furthest points from the sea/land: https://en.wikipedia.org/wiki/Pole_of_inaccessibility

Latitude and longitude integer degree intersections around the world: http://confluence.org/

The integer degrees is arbitrary, but it provides a random sampling of landscapes. I like the idea of going out to find some defined spot, like geocaching without any caches. It also provides a page of antipodes photos, places exactly on the other side of the earth from each other: http://confluence.org/antipodes.php

Must also mention earth sandwiches: http://www.zefrank.com/sandwich/

Fun fact: there are parts of the Pacific ocean that are opposite each other, therefore the Pacific ocean spans (not covers) half the globe.
