2) Shimano, between Tali Karng and Miller's Hut - and I mean a direct line between the creek end of Tali and the Hut.
3) Polaroids, on a line due east from the head of Pilot Creek, above the halfway point to the saddle.
4) El cheapo mirror with metal frames, somewhere on the Paralyser, probably between the western trig and Illawong Hut.
