raised beach

A beach raised above the present waterline and wave action of a lake, river, or ocean, consisting of an accumulation of water-worn stones, gravel, sand, and other shore material, is called, naturally, a raised beach. The raised shore may be formed by the elevation of the coast or left by receding waters, as in many lake and river regions. A raised beach in a boreal forest is a sometimes called a stranded lakeshore. Such shores exist in significant numbers, particularly since boreal forests make up more than one-third of northern hemisphere forests. In the southeastern United States, raised beaches, regionally called beach ridges, were formed by higher sea levels that occurred during interglacial periods of the Pleistocene. They are often many miles from the present-day coastline, and may be marked by the existence of dune systems.
