What are some local examples of landforms formed by deposition or erosion in Portales NM?

Some landforms created by erosion are platforms, arches, and sea stacks. Transported sand will eventually be deposited on beaches, spits, or barrier islands. The major deposition landforms are beaches, spits and bars. Deposition occurs when wave velocities slow, or when ocean currents slow due to encountering frictional forces such as the sea bed, other counter currents and vegetation.
