Airport
Pine Ridge airport (IEN) does not have any runway markings; including runway designation; center-line; touchdown or edge markings. The airport beacon rotates but does not illuminate. The windsock is in poor condition; preventing determination of direction or approximate velocity of wind. The runway appears to have been recently re-sealed. During night operations; it is very difficult to identify the touch down point and determine height above runway during flare.Ensure appropriate agencies are informed and needed corrections made.
Pilot reported runway marking issues at IEN airport.  Reporter also described issues with the rotating beacon and windsock.
