Huh. Funny Brian should ask...

I had to check a map to make sure.

Yep, in this image, I was parked right exactly on the Atlantic Branch of the Continental Divide. Which means, all that snow on the right (and the hillside beyond) is gonna flow into the Great Divide Basin when it melts, and go nowhere, but all that on the left is gonna run down into the Missouri River basin.

Hope you folks don't mind a little extra this year...
