Thesaurus is your friend.

As said already, you do not always have to use the explanatory part of the name (forest, wood, mountains, etc).

Sometimes a place can gain a name of it's own based on events that transpired there. It may not have anything to do with it's being a mountain, field or whatever. "You don't want to go in there my friend, there is a reason they call it..'Widowmaker.'"
