It is a sand dune.
Wind erosion and deposition may form sand dunes and loess deposits. When the wind strikes an obstacle, the result is usually a sand dune!

Your question doesn't make sense to me . . . maybe you meant, "How does a loess (luss) deposit form?" Loess is a deposit of dusty silty dirt that has been blown into an area from a different location. It often deposits in the shape of sand dunes. The "Palouse Loess Deposit" around Pullman, WA and Moscow, ID is a great example of dune-shaped loess deposits.
