I'm back folks with another flower that has stumped me. I am pretty sure it is a Draba, but I won't bet on it. I have not been successful at pinning it down any farther than that. The flower was growing in a sandy soil across a gravel bar of the Colville River north of the Brooks Range, Alaska. We were somewhere around 30 miles from the Arctic Ocean. The picture was taken July 21, 2007.
