This is where the Eramosa River flows into the Speed River, and is a prominent river confluence in the heart of Guelph. The meeting of these waterways has been a gathering place for Indigenous peoples for generations, reflecting deep cultural and spiritual connections to the land. Later, the rivers played a key role in shaping the city’s early industry, providing power for some of its first mills and businesses.

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".

Mountain Biking purists will love riding on any one of the trails like the Wandering Lynx Backcountry or the Bent Rim. Riders will love how they are deeply immersed in quiet forests. Hikers, horseback riders, and families: there are still tranquil trails and water features like the Hilton Falls, or the reservoir to experience quiet nature, and of course, to snap the perfect picture for your Instagram. If you like to explore, rumour has it geocaches are hidden around Hilton Falls. Once you’ve found a hidden treasure, look out for birds like the Hooded Warbler, and flowers like the Michigan Lilies. Bring marshmallows and roast s’mores with the family near the falls itself. You’ll learn a little history about the escarpment and previous inhabitants: the Mill Ruins are still there to this day! As the sun sets, hike to the reservoir and fish in the water.
