This is Coal Creek near Lafayette, Colorado. The creek is running really high right now - I had to finish this one before the afternoon thunderstorms started to build-up. We never ended-up getting any rain, but it sure looked threatening for a while.
Sometimes you can't always wait for a sunny day to paint - although around here you usually don't have to wait long. Despite the clouds, I managed to make it over to the foothills at the edge of Boulder to do a couple of paintings. This one was done near the base of the Flatirons above Chautauqua Park - looking out over the city of Boulder. The red in the middle-ground is the red tile of the University of Colorado buildings.
