The Cheltenham Badlands showcase a vibrant landscape of exposed Queenston shale that was formed around 450 million years ago at the bottom of an ancient sea. The trails that run through the site offer hikers dramatic viewpoints as the terrain winds past gently eroding ridges and gullies. Visitors must reserve a parking spot in advance, and staying on the designated pathways is essential to preserve the fragile geology of this provincial natural landmark.

Translation of the information board Crawford Lake is a unique body of water referred to as the Meromictic Lake. In a meromictic lake, the water in the lower half of the lake does not mix with the water in the upper half. This results in a condition that preserves sediments in light and dark layers at the bottom of the lake. By examining the strata, scientists can learn about changes in climate, vegetation, human habitation, and atmospheric chemistry. Crawford Lake has garnered international attention as one of ten locations (including the Great Barrier Reef, the Baltic Sea, and the Antarctic Ice Sheet) that could be used to officially mark the end of the Holocene Epoch and the start date of the Anthropocene Epoch. This marker of change is known as the "Golden Spike".
