在密歇根湖的一些水下阶地上，沙脊一侧是陡坡，另一侧是坡度。这些沙脊的起源和行为是与一个c级海滩尖端有关的。描述了一种类似的更大规模的沙子水下质量运动！因为它发生在一个大的尖头突起，如斗篷。了解水下沙丘的性质，对于解释交错层理的普遍存在、波痕和其他底部不规则性的保存以及有机遗迹和其他物体在沉积物中的埋藏具有重要意义。
Sand ridges having a steep slope on one side and a gradual slope on the other occu on some subaqueous terraces in Lake Michigan which have a plentiful supply of sand The origin and behavior of these ridges is explained in connection with one class c beach cusps. A similar subaqueous mass movement of sand on a larger scale is describe! as it occurs off a large cuspate projection such as a cape. An understanding of the be havior of subaqueous dunes is important in explaining the common occurrence of cross bedding, the preservation of ripple marks and other bottom irregularities, and the em bedding in sediments of organic remains and other objects.
