They sort of look like the dark brown mountains in this map. And yours are obviously way better drawn.

I see what you mean - those and mine are both variants of the old caterpillar style of mountains. Think caterpillar style but add in ridge lines.
It's a good style for top down, as you can convey some things about the size, width, and to some degree the height of the mountains.
Done loose, it can also be a relatively fast way to do them... well, relatively... once you start shading them and adding highlights.. well, not so fast anymore.
