If you're like me you look at a stream and wonder where it comes from or where it goes. The National Atlas has a new tool called Streamer. Click on a stream and you can trace it up or downstream. Here is the path of Butternut Creek in Charlotte, Michigan to Lake Michigan.
Tracing upstream is much more complicated. You get all the possible tributaries above you. Here's a trace of the Tennessee River near its mouth in Kentucky.
Unlike Streamer, rivers do not care about national boundaries. If you trace the Pend Oreille River downstream from Idaho, you get stuck at the Canadian border in Washington. The river itself only makes a short trip into Canada where it empties into the Columbia and heads right back into Washington but this is not shown in Streamer.
I like a good long windy path like the one made by Cassadaga Creek south of Buffalo. It starts just a few miles from Lake Erie but goes the other way instead.
Or Wyoming's Wind River.
Pick your favorite river (if you have one) and give it a try.
