The Alum Hill Deep Cut is a half-mile stretch where the canal and towpath pass between two vertical shale cliffs. The area is marked with small shards of rock along the towpath, and while passing through on long bike trips this section always seemed to say, “Welcome to Oldtown!” Although it’s another half-mile to Lock 71 and the watered section of the canal, the deep cut has its fair share of slimy, green water. From here to the Lockhouse (heading downstream), the ducks and turtles were too numerous to count. I was surprised to see ducks posing on branches sticking up out of the water, but, unfortunately, my camera hand wasn’t nearly quick enough to catch them. Today, I was even too slow on the draw for the turtles. Bummer!
