`terrain.elevation_mountain`Elevation

Default: 0.0

What it does

Sets how far up the land mountains are allowed to start. And mountains don't stack on top of hills

What you see

Raise it and peaks retreat deep inland, push it negative and ridged, craggy ground spreads across much more of the island.

Gotcha

One side of every map (the low-loot side) never gets mountains no matter what you set. the game hard-blocks them there.
