>>> Continental Divide

Not our usual type of link for Craft A Craft, but given that I’m both a "boat guy" and a "computer guy" I found this of lots of interest. Its a "dissertation" with lots of pictures and the like on how to compulationally find the actual continental divide (i.e. the point where water will either flow to the Atlantic or the Pacific if in the United States).

One piece of trivia mentioned was that at one point in South America, the continental divide is actually under water and you can sail over it.
