I found this interesting. It might be useful if you're building procedural planets.
"The analysis showed that mountains had a significant land area up to their snowlines, after which it dropped rapidly. In general, mountains only rise to around 1,500m above their snow lines, so it is the altitude of these lines — which depends on climate and latitude — which ultimately decides their height."

Thanks for the share this is useful. Though their conclusion seems to be somewhat common sense as the snow/ice buildup would be thicker in such colder areas for such erosion. Haha. Going to try adding some separation like this in the planet i'm working on.
thanks Matt.
