So today’s geeky book research tells me that the hierarchy of rivers can be described by something called a Strahler number, better known (on the Internet, anyway) as stream order. Basically, as smaller streams feed into larger ones, the stream’s Strahler number goes up, at least when streams of similar lineage are meeting.
The Mississippi has a Strahler number of 10, the highest in the United States. The Amazon has a Strahler number of 12, the highest anywhere.
Information on their Strahler-Bacon numbers still to come, no doubt. But first, I need to go rearrange the statues in Central Park, because writing is fun that way. Back in a few.
