Show HN: Algorithmically Finding the Longest Line of Sight on Earth

With the help of a custom-developed algorithm, CacheTVS, we have exhaustively checked every single view on Earth in search of the coveted longest line of sight on the planet. Based on the method we detail here, we present the greatest view of all:

1. Hindu Kush to Pik Dankova (530km) ↗

Longest Line Of Site
The longest line of sight on the planet, at 530km, from the Hindu Kush to Pik Dankova

Runners Up

Longest lines of sight tend to group together around peaks and ridges. So the following are more of our own curated list rather than the technically correct runners up. We chose them based on being in notably different regions of the world.

2. Antioquia to Pico Cristobal (504km) ↗

Second Longest Line Of Site
The second longest line of sight, at 504km, from Antioquia to Pico Crostobal in Colombia

Now we go right to the other side of the world to Colombia in South America. We’ve found a line of sight from the department of Antioquia to Pico Cristobal, Colombia’s highest mountain.

3. Mount Elbrus to the Pontic Mountains (483km) ↗

Third Longest Line Of Site
The third longest line of sight, at 483km, from Mount Elbrus in Russia to the Pontic Mountains in Turkey

Our pick for the third greatest view is from Mount Elbrus in Russia to the Pontic Moutains in Turkey. Notably Russia does not share a land border with Turkey, so it’s interesting that you can still see one from the other.
