This is my contribution to the One Word Sunday prompt Skyline.
I decided to go with a local skyline with some interesting geology.
This is the Niagara Escarpment in autumn with Wiarton Marina below. This is the same escarpment the the Niagara River flows over at Niagara Falls on the Canada/U.S. border. The escarpment starts and ends in the U.S. after traveling across part of southern Ontario and forming the eastern side of the Bruce Peninsula. You can see sections of the limestone face of the escarpment through the trees.
