Description Sandbanks Provincial Park is located on the northern shore of Lake Ontario in Prince Edward County south of Picton, Ontario, Canada. The park measures in size. It is noted for its picturesque sand dunes and beaches and contains the largest bay-mouth barrier dune system in the world. This formation is created by longshore currents flowing from west to east along Lake Ontario's northern shore. Some dunes can reach high. The dune system stretches roughly long from the tip in the northwest less than wide to a swath in the southeast. The dunes run from Lake Ontario into West Lake. Behind the barrier dunes lies a series of foredunes that is sparsely vegetated and further back, pannes, back dunes, and reforested sand ridges. County Road 12 in Prince Edward County, stretching from The Outlet, Ontario to Bloomfield, Ontario, runs through the park. Flora and fauna Plants native to the sand dunes include sea rocket, American beachgrass, tall wormwood, Russian thistle, sand cherry. In the pannes, sedge and rushes are the most common, along with orchids, purple gerardia, Kalm's lobelia, silverweed and twayblades. In the forested areas, creeping juniper, white cedar, eastern hemlock, sugar maple, balsam fir, white spruce and three types of pine tree are common. Prairie species are also found within the park, such as hoary puccoon, sand dropseed, and butterflyweed. Animals found within the park include a number of shorebird and amphibian species, along with largemouth and smallmouth bass, yellow pickerel, northern pike among other fish. History The dunes were formed by glaciers 12,500 years ago. In the 1880s, due to a combination of timber cutting and poor farming practices, the soil inland from the sand dunes had become destabilized and the sand dunes were able to drift inland, increasing in size. In 1881, the West Point Road was buried under of sand and the town of Athol, Ontario was forced to relocate after facing a similar event. In the 1920s, Sandbanks was the site of an intense reforestation project. The sand
