Rock Glen Conservation Area

Rock Glen Conservation Area is a protected natural space in Lambton County featuring a waterfall, walking trails through forested areas, and exposed fossil beds along the steep walls of Ausable Gorge. The landscape reveals layers of rock that tell the story of this region's ancient past.

The site developed as a conservation area in the 1970s and later added a small museum to showcase fossils and artifacts spanning different time periods. Ausable Gorge formed over millions of years through river erosion and now serves as a window into the past.

The Arkona Lions Museum exhibits Devonian period fossils, Aboriginal artifacts, and Clovis Point Meadow Cache Blades from early First Nations settlements.

Visitors should wear sturdy footwear and bring weather protection, as trails descend into the valley and can become slippery when wet. The site lies along a river valley, so checking conditions and arriving early is wise, especially on warmer days when crowds gather.

Visitors are allowed to collect and take home marine fossils from the Devonian period, an activity uncommon in most protected natural areas. This opportunity makes the place unusual for fossil enthusiasts of all ages.
