Shoals are shallow areas formed by sand, gravel, or other unconsolidated sediments, and are important coastal terrain features that influence navigation, ecology, and mapping. They are similar to reefs in that both are hazards to ships, but shoals differ because they are sedimentary and dynamic, while reefs are rocky and more permanent.
Shoals often form near river mouths, barrier islands, or along coastlines where currents and tides deposit material. They rise close to the water’s surface and may even be exposed at low tide. On nautical charts, shoals are carefully marked because they pose dangers to boats.
Note: Not all Terrain Features have official place names. Even there are many Shoals located throughout Pictou County, very few have names included in the Canadian Geographic Names Database., if you know of some with local names that we have missed, then we encourage you to share that information with us so we can add the info to the atlas.

The Flats in Amet Sound, off Cape John, are a shallow shoal formation that plays a defining role in the coastal geography of the area. Situated near the eastern entrance of the Sound, The Flats are a broad, submerged sand and gravel shoal that extends outward from Cape John into the sheltered waters of the sound. Their presence has long influenced navigation, as the shoal creates shifting shallows that mariners must account for when entering or leaving the sound.
The Eastern Peak is a submerged shoal feature within Amet Sound, positioned just off Cape John, it has long been noted on nautical charts as a hazard to navigation. This feature, marks one of the shallowest points in the approaches to Amet Sound. Rising abruptly from the surrounding seabed, the peak is composed of rocky outcrops tied to the Cape John Formation—a Carboniferous sandstone and conglomerate unit that underlies much of the peninsula.
The Amet Island Shoals are a cluster of shallow, rocky and sandy formations lying just inside the entrance of Amet Sound, off Cape John in Pictou County, and have long been recognized as a defining navigational feature of the area.
Dulse Rocks is located just off of Olding Island in Merigomish Harbour.
The Rock Pile is a well‑known shoal within Amet Sound, lying just off Cape John, it has long been marked on nautical charts as a navigational hazard. This submerged terrain feature consists of a cluster of rocky outcrops and shallow ledges that rise close to the surface of the water, creating a natural obstruction for vessels entering or leaving the sound.
Sutherlands Shoal is located in the Northumberland Strait, north of the Toney River area.
Murdock Shoal is located in Pictou Harbour.
Mackenzie Shoal is located in the Northumberland Strait, just outside the mouth of Pictou Harbour.
