thanks again, rounser. information like that is great for any amateur mapmaker/worldbuilder.rounser said:Okay, a quick search yielded the answer....a typical size of a mountain or small group of mountains is about one to ten kilometres across, or one half a mile to six miles across...another source said that they can range up to 24 miles in diameter...and are a minimum of 1000 feet high (one fifth of a mile high). Hope this helps someone...
