Depending on currents and the shaped of a shoreline, waves will sometimes deposit silt, sand, and gravel at a particular spot. This gives rise, over the course of millennia to a “tombolo”. A tombolo is a sandbridge connecting one island to another, or to a mainland. A tombolo is what saved Presqu’ile (in Lake Ontario) from being just another island. Similarly, a large tombolo has altered the geography of this island in Swell Bay. Tombolos are rare in this region. This one features raised beach ridges that are likely related to phases of ancient Lake Agassiz.
