Fig. 1. LOOKING S.S.W. FROM CAPE ROYDS ACROSS THE 

 NOW NEARLY SNOW-FREE SURFACE OF KENYTE 

 The heaviest snow-diifts are on the north-west sides of the slopes. To the 

 right is a broad U-shaped hollow eroded by an ancestor of the Ro.ss Barrier. 

 To left of centre on horizon is Inaccessible Island, with Tent Island at 

 the back of it ; then to the left, more distant, is Razorback Island, then 

 Cape Barne and Cape Barne Pillar
