[5] Civilization around Rock Glen dates back to the time when Paleolithic or Early First Nations peoples used the nearby hills to hunt the barren ground for caribou some 10,000-years-ago.

The most commonly found fossils are brachiopods, horn corals (Heliophyllum halli), and crinoid stem sections; which are remains of the marine life of the Devonian period.

In response to complaints from anglers that fish were unable to travel upstream to spawn, a Canadian Army demolition squad blew up the dam with dynamite.

[4][7][16] The conservation area is home to a large diversity of species representative of both zones, and are found alongside sugar maple, beech, white elm and basswood.

Located on the conservation grounds is the Arkona Lions Museum and Information Centre, which contains a large collection of birds and wildlife preserved with traditional taxidermic methods.

The museum also has a large collection of fossils and artifacts found on or near the conservation grounds, and holds presentations and guided tours there for visitors and schools.

The grounds also has many stairs, boardwalks and bridges allowing visitors to safely explore the steep sides of the glen and the 10.7-metre high waterfall just upstream of the Ausable River.
