Abstract Feather-like dunes was named from its feather-like shape. In this paper, topographical features of feather-like dunes was measured by total station instrument in the Kumtagh Desert, and the profile characteristics of feather-like dunes was analyzed. (1)The direction of "quill" of feather-like dunes was N55°E, and the "quill" was composed of crescent dunes ridges with the average height of 17.65 m, and the average length of northwest wing was 72 m, longer than southeast wing. (2)Great fluctuation was found from the profile of the "quill", the wave length was 50-100 m, and the wave height was 10-25 m. (3)The average width and slop of the "quill" were 127.69 m and 12.59, respectively. The average length and slop of northwest slope were 71.74 m and 11.65, respectively. The average length and slop of southeast slope were 50.09 m and 13.52, respectively. (4)The "plume" of feather-like dunes was composed of large dome sand dune waves, not a feathery pattern of light and dark as remote sensing image showing. The average width of the large dome sand dune waves was 641.34 m, and the profile was relatively flat. The distance between two sand waves was about 400 m, and the wave height was about 1-3 m, the average slop length and average slope were 322.37 m and 1.28, respectively.
