Hazy Potomac River work in progress

The other day I got out for a lunchtime hike along the Potomac. It was a bit eerie being the only out with a hazy river. I liked the warm colors in the distance and the very cold appearance of the foreground. Still a lot more to go on the the web of trees and branches and the rocks on the ground. This one is all ultramarine blue, burnt umber, and yellow ochre.
