False 1623-153 ~200m on 013° magnetic and +03° from Bunter's Bulge (Weiße Warze). From Weiße Warze, follow red arrows until you see yellow arrows, follow these (there would seem to be just two of them). After last yellow arrow, cross gully in same direction, then permanent survey mark TC is on large slab in centre of next depression. From here, climb out of depression on bearing 035°, then keep going up gully to 153 (large boulder above on left is a good vantage point). S gps00.153 post selective availability GPS
