Crawford Lake is much more unusual than it first appears. Its upper and lower waters never fully mix, making it a rare meromictic lake, and the yearly sediment layers on the bottom preserve an incredibly detailed environmental record. A newly rebuilt boardwalk now circles the shoreline, with interpretive signs explaining the lake’s ecology, scientific importance and Indigenous history.

Between the years 1835 and 1867, three different sawmills were operated at this location on the upper reaches of Sixteen Mile Creek. The ruin of the mill next to Hiltons Falls at the foot of the rock formation gives an impression of past times. Source: Information boards (Visit on June 17, 2026)

The Hilton Falls Reservoir in the Hilton Falls Conservation Area was completed in 1973, primarily for flood control on a tributary of Sixteen Mile Creek. Further west in the Conservation Area, another creek flows over Hilton Falls, a waterfall on the Niagara Escarpment rock formation into the valley. From the dam, there is a good view of the body of water to the northwest, which is nestled in a dense forest. To the southeast, the rock formation of the Kelso Conservation Area is visible.

The water of the Sixteen Mile Creek's headwater stream cascades down the rocks of the Niagara Escarpment in a nameless waterfall and flows into the Hilton Falls Reservoir. To reach the waterfall, one leaves the Red Oak Trail north of the reservoir onto a side trail of the Bruce Trail, which leads back to the visitor centre above the Niagara Escarpment. Views of the waterfall from above are not possible in its entirety; the view of the reservoir is obscured by the dense green foliage of the trees. (Visit on June 17, 2026)

Vernal Pools - also called temporary wetlands - fill up with winter rain and spring snowmelt. These wetlands usually dry out by mid-summer. They offer a special habitat for salamanders, frogs, and invertebrates. Source: Information sign (Visit on June 17, 2026)

The Hilton Falls are the main attraction of the Hilton Falls Conservation Area. The water of a source stream of the Sixteen Mile Creek plunges ten meters over the rock formation of the Niagara Escarpment. You can view the waterfall from both above and below. https://www.gowaterfalling.com/waterfalls/hilton.shtml (Visit on June 17, 2026)

Can’t really see the waterfall other than from the top of it but it is still pretty.

Translation of the information board Crawford Lake is a unique body of water known as a 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 studying the layers, scientists can learn about changes in climate, vegetation, human settlement, and atmospheric chemistry. Crawford Lake has gained 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 determine the official end of the Holocene epoch and the start date of the Anthropocene epoch. This marker of change is known as the "Golden Spike".
