Re: Definition?

That's the problem that I am having. It's easy in states like Wyoming where the 2nd and 3rd high points are unique mountain summits seperated by miles, however in places like Iowa it's hard to determine where Hawkeye point ends and a seperate high point begins on a neighboring hill. I'm looking for ideas and suggestions about how to determine these 2nd and 3rd high points so that I can be consistent across the U.S. One rule that I have established is if there are two seperate points with similar elevations then I'll try to visit both of them to make sure that I get to the "true" high point.
