...sand brought up the windward slope. When this depositional slope is steepened to the angle of repose of dry sand (about 32°), this angle is maintained and the added sand slips down the slope or slip face. When this happens, the dune form is in equilibrium, and the dune moves forward as a whole, sand being eroded from the windward side and deposited on the lee.
The side of a sand dune facing the ocean is called leeward.
The upwind direction of a sand dune has a gentle slope. A steep slope is on the downwind side. The pronounced slope of a sand dune is called a slip face. Sand erodes from the wind off the slip face. To learn more about sand dunes, visit http://www.tulane.edu/~sanelson/geol111/deserts.htm.
A sand dune that got blown away
The tallest sand dune is in Great Sand Dunes National Park in south-central Colorado. It reaches about 750 feet above the San Luis Valley floor.
is more steeply sloped than the windward side

its either on a slip face, crest, windward slope, or any area of a dune
Slip face.
The leeward side of a dune is shorter and called the slip face. Dunes often serve an important purpose in protecting land from storm waves.

The gentle slope is in the upwind direction. The downwind direction has a steep slope called a slip face.
A sand dune is a desert feature that forms as a result of wind or rain action towards one side. The sand dune usually forms towards the dominant side of the wind direction and can vary in gradient.
