One afternoon in May I went to the shore of the Rideau River at Carleton University. The waters are wild and fast, still carrying the energy of Hog's Back Falls upstream. They pass beneath the railway bridge that carries the commuter O-Train through campus. Compare these views to a post from winter.
This last shot is from a few days ago, taken from on board the O-Train as it passes over the river. I have taken this view before in the winter.
