[edit]DescriptionWhirlpool Sandstone (Lower Silurian; The Whirlpool, Niagara River, New York State, USA) 2 (46835525901).jpg |
Sandstones in the Silurian of Ontario, Canada. The Whirlpool Sandstone is a fluvial to very shallow marine unit of Early Silurian age. During high flow (= natural flow), these ledges are usually covered with water. The Canadians have been diverting water from above Niagara Falls (= upstream from this site) for a long time. Stratigraphy: Whirlpool Sandstone, lower Medina Group, lower Rhuddanian Stage, lower Llandoverian Series, lower Lower Silurian Locality: riverside outcrops along the southeastern banks of the Niagara River (as seen from Whirlpool Point), immediately downstream from The Whirlpool, American side of the river, far-western New York State, USA |
