Rockhounds will find a rare treat in the Cypress Hills Interprovincial Park, spanning Alberta and Saskatchewan: the Conglomerate Cliffs.
Cypress Hills covers about 2,600 square kilometres (1000 square miles), reaching altitudes of about 1,400 metres (4,500 ft). The formation was created when glaciers pushed the surrounding terrain up. It's known to be less effected by erosion than the surrounding plain, and about 200 sq km (80 sq mi) on the Alberta side was also left untouched by glacial erosion.
On a recent visit to the park, I had the chance to explore the Conglomerate Cliffs, a unique area looking down some 30 m to Adams Lake. This area is located a short drive from the Fort Walsh Historical Site.
The surface of the Conglomerate Cliffs is made up of a combination of gravel and stones known as "cobbles."
In turn, this conglomerate material resists erosion by wind or water, protecting the softer rock formations underneath and preventing the cliffs from eroding.
It's well worth exploring the footpath leading down from the cliffs for interesting and unexpected details, like this rock "cave."
Here are some of the sights along the path.
