Mountain-climbing sand dunes (also known as climbing-falling dunes and headland-by-pass dunes) are rare and interesting natural phenomena that only occur when a particular combination of circumstances exists. These circumstances are: a supply of sand that is continually renewed and blown by strong prevailing winds, and a hillside, cliff or mountainside that is downwind of and intercepts and traps the wind-blown sand forcing it to climb the hill or mountain slope, thus forming the climbing dune.
