About Swallow River Falls
Swallow River Falls is a forested-river waterfall located near Marathon, Ontario (approx. 40.5 miles / ~65 km from Marathon). The falls sit on the Swallow River and appear as a series of cascades and drops through a bedrock channel surrounded by mixed boreal forest. Flow and appearance can vary seasonally, highest flows are typically in spring snowmelt and after heavy rains, while late summer flows may be reduced. Exact measured height is not confirmed here.
The Setting
Swallow River Falls sits at 200 metres within Pukaskwa National Park, in the foothills of Ontario. The falls drop 2 metres.
Why This Waterfall Exists
Swallow River Falls flows over hard intrusive rock laid down over 2.5-2.8 billion years ago. These resistant rocks form a durable ledge that water cannot easily wear away, creating a 6-foot drop where softer material downstream has already eroded.
