A gravel bar is a hydrogeologic sediment composed of gravel, and is prone to continuous erosion and meandering due to fluid dynamics. Gravel bars are typically found in the slowest moving, and shallowest parts of water bodies.[1] Gravel bars in rivers and streams are parallel to the shore, furthest from the thalweg.[2] Gravel bars are also located in Arctic waters, devoid of sandy sediments. One example is Oodaaq, which is often argued to be the northernmost point in the world.[3]
