I know there is not enough to ID but thought I'd share. I used to hike the oil shale cliffs behind the Job Corps Center out of Colbran, Colorado, back in the 70s. The size of the scales on this fish were such that I knew it would be a keeper if I caught it. The oil shale there is such that you can actually light it and it burns. (The little one on the right I found out of Eden, Wyoming, sometime in the 80s).
