Part of it is the continental divide. After that it looks like there are several stories of how it was determined but basically it follows the Bitteroot Mtns.. Just for the record, I only know that because I looked up, the border between Idaho-Montana. It was an interesting read.
Yes a lot of it is ridge tops of mountains. Continental divide and Bitteroots. |
