27" brown trout, my largest ever. It was the sub-dominant fish in its pool. After this, I hooked the bigger one, but I couldn't land it.

I was leading a Canoeing trip through Northern Minnesota and one of my students claimed they saw one of what is drawn in the picture in a little pond. The only picture we have is the one the student drew. Any guesses on what he saw?
