A dune is a landform composed of wind- or water-driven sand. It typically takes the form of a mound, ridge, or hill. An area with dunes is called a dune system or a dune complex. A large dune complex is called a dune field, while broad, flat regions covered with wind-swept sand or dunes, with little or no vegetation, are called ergs or sand seas. Dunes occur in different shapes and sizes, but most kinds of dunes are longer on the stoss (upflow) side, where the sand is pushed up the dune, and have a shorter slip face in the lee side. The valley or trough between dunes is called a dune slack.

The Algodones Dunes is a large sand dune field, or erg, located in the southeastern portion of the U.S. state of California, near the border with Arizona and the Mexican state of Baja California. The field is approximately 45 miles (72 km) long by 6 miles (9.7 km) wide and extends along a northwest-southeast line that correlates to the prevailing northerly and westerly wind directions.

These sections include Glamis, Gordon's Well, Buttercup, Midway, and Patton's Valley.

Fossil Lake is a dry lakebed in the remote high desert country of northern Lake County in the U.S. state of Oregon. During the Pleistocene epoch, Fossil Lake and the surrounding basin were covered by an ancient lake. Numerous animals used the lake's resources. Over time, the remains of many of these animals became fossilized in the lake sediments. As a result, Fossil Lake has been an important site for fossil collection and scientific study for well over a century. Over the years, paleontologists have found the fossil remains of numerous mammals as well as bird and fish species there. Some of these fossils are 2 million years old.
Baert Lake is a small artificial lake in the unincorporated community of Christmas Valley in the U.S. state of Oregon.
