Changing Forest to rocky terrain

[Guest ledzzepplin]

I often fly in the area of the White Mountain range in New Hampshire. In FSX, using GEX and UTX, Mt Washington is depicted as being forested right to the summit. In reality, the top third of this mountain is mostly rock and barren of trees and vegetation. How could I got about changing this land class in FSX?Thanks!

I think there is a version of EZ-Landclass for FSX. Alternatively a tool like SBuilderX or FSX KML should be able to do something like that
