No Man's Sky

The mountain is so high that it reaches the clouds. But what's even more special is that for some reason, it's one of like a very few mountains on the planet - it's freestanding. You can actually even see the planet's curvature with it.

I think that if you were to build a base there, you could probably reach for the sky.

Coordinates +0.22, -83.38. Planet's called Yannet Minor. Dissonant sentinels, pretty hot.
