What is a Karst?

Before diving into the wonders of Eramosa Karst, it's helpful to understand what a karst is. A karst landscape is formed from the dissolution of soluble rocks, including limestone, dolomite, and gypsum. It is characterized by underground drainage systems with sinkholes, dolines, and caves. Eramosa Karst contains examples of more than a dozen different karst features, making it a significant educational and geological site.

The Discovery of Eramosa Karst

The Eramosa Karst lands were officially recognized in 2003 when these lands were acquired by the Hamilton Conservation Authority. The area was opened to the public in 2008, providing an accessible way for visitors to explore its unique topography.
