About Grand Sault
Grand Sault (Grand Falls) on the Saint John River is the dramatic waterfall and gorge adjacent to the town of Grand Falls, New Brunswick. The site features a wide, powerful drop where the river cuts through a steep gorge; flow is typically highest in spring during snowmelt and during periods of high rainfall. The falls are a prominent local landmark with municipal viewpoints and park space overlooking the river and gorge. Exact waterfall dimensions vary by source; the drop is commonly described in local material as being on the order of tens of metres (roughly 60–80 ft), but that figure is not confirmed here.
The Setting
Grand Sault sits at 121 metres in the coastal lowlands of New Brunswick. The falls drop 23 metres.
Why This Waterfall Exists
Grand Sault flows over layered sedimentary rock laid down about 252-539 million years ago. Over time, the stream has worn through these layers at different rates, creating a 75-foot drop that forms the waterfall.
