As one starts to descend into a closed depression, a 4m x 5m choked surface feature was examined in an area of steep clints, with fluting on a couple of walls, and a small tree on one side. Boulder floor, but possible weak draft out at lowest point (cool day on surface). Recorded to eliminate having to be examined again !. [Patrick Warren]
