Karst 2021

13 images Created 13 Apr 2020

This series of photographs documents a unique limestone landscape, known as a karst. This local landform provided a multitude of subject matter incorporating the shapes, colours and patterns of the limestone rocks, the kettle formations, numerous fissures (cracks in the rocks), small caves, tall White Cedar trees (Thuja occidentalis) and unique mosses, algae and ferns. The White Cedar trees dominate this environment amongst the rocky karst terrain, growing straight and tall within the shallow limestone soil.

A Karst landform is a rocky dominated topography found in specific locales throughout the world and is characterized by an outcropping of limestone rock (also known as chalk or calcium carbonate). Karst is associated with a variety of underground caves, porous underground fissures, and landforms called rockmills or kettles, sinkholes and underground streams. Kettles, including those smaller ones found in the local Karst I documented, are swirled holes in the limestone rock that have been created by harder granite rocks being pushed by the fast flowing water of a large river. In the Kawarthas this river was called the Kirkfield Outlet, which was a fast flowing prehistoric river linking two ancient lakes called Lake Algonquin to the north and Lake Iroquois to the south. Both of these lakes were the result of melting and receding glaciers.

The Karst landform depicted in this series of photographs is the best representative of this unique landform in the Kawarthas. It gained my attention because it is a quiet and peaceful place to commute with nature. The small ravine backing onto a river shelters you from the natural elements and is a protected place of solace. A multitude of photographic possibilities exist, as the rocks protruding out of the ground act as a giant puzzle to be solved and ordered in the camera. Each of my many visits to the Karst brought new possibilities, as even the slightest change in angle revealed potential new photographs. Knowing a location well by many visits over time reveals much to the photographer and generally results in better photographs.
