Columbia River

The Columbia River System
Daniel Huffman has developed a new technique for drawing maps of river systems. Actually, he has adapted an old technique that was developed to portray subway systems. It's kind of nice because you can see at a glance which rivers are connected to each other, something that can extremely tedious on conventional maps, especially those produced by Google.

Hi Chuck,

I love this diagram. Thank you.

BTW, I just became aware of another way in which Oregon is somewhat unique:

Interesting quote from the article:

You see, the vast majority of U.S. states, including Washington, have what are called “permissive” rules, allowing drivers to enter an intersection during an entire yellow interval. (A violation occurs only if a driver enters after the onset of red.) Not Oregon. It’s one of only 12 states with a “restrictive” yellow-light rule, which essentially translates into “a solid circular yellow means stop and red means stay stopped.”

==>> a “restrictive” yellow-light rule?

I had no idea such a thing existed. I'll definitely keep that in mind the next time I'm there.
