LS.0005-00Christine Smith-Siddoway, Investigator on US National Science Foundation research grant, in a huge wind-scoop in Arthur Glacier on Mt. Little. Dark brown planar surface beyond her shows the shear fractures and faults she was studying to reconstruct previous tectonic activity in the area. The rock is Late Cretaceous Byrd Coast Granite. West Antarctica.
LS.0008-00Mike Roberts on the summit pedaplane of The Billboard, with Mt Rhea in background. The peaks of Western Sarnoff Range are composed of Late Cretaceous Byrd Coast Granite. On right is Boyd Glacier. Left is the Arthur Glacier. Far distant peaks:(centre) E. Sarnoff Mts. & (left) Denfield Mts.
LS.0009-00Traversing back to Mt. Rea from The Billboard, a magnificent chunk of Late Cretaceous Byrd Coast Granite at western end of Sarnoff Mountains. It has shear walls except for ramp in centre of picture. Right is Arthur Glacier & left is Boyd Glacier. Sulzberger Ice Shelf in background.
The summit slopes of Billboard are a very old erosion surface. W.Antarctica.
LS.0011-00Raised tracks in the snow after a storm. Most storms in the Ford Ranges come in with strong winds, which drift piles of snow up around camps. The end of the storm is often marked by a wind shift, which in this case eroded the storm drifts away, leaving only these hardened footprints.
