western coast of Palmer Peninsula (Pig. 2k). The ship sailed southvard 

 along the coast, passing through two-foot thick ice of concentrations of 

 six- to ten-tenths to the vicinity of Renaud Island. South of this to 

 Adelaide Island, ice under pressure reduced shipte movement to a minimum. 

 West of Adelaide, ice conditions improved as six-tenths concentration 

 was reported on 5 March. At this time, GLACIER met the Chilean ice- 

 breaker, ARA GENERAL SAN MARTIN, and escorted her to open water. GLACIER 

 turned southward, following leads through ice of six- to eight-tenths 

 coverage and reached the Danish vessel, MV KISTA DAN, at 68 °S, 71^7, on 

 6 March. By 8 March, pressure on the ice field diminished sufficiently, 

 and the pack opened enough for GLACIER to escort the vessel to open water. 

 GLACIER then proceeded to Deception Island. Open water prevailed except 

 in the passage between Anvers and Brabant Islands and DeGerlache Strait, 

 where six- and four-tenths of brash and block were encountered, res- 

 pectively. The last ice observed consisted of a few icebergs and shore- 

 fast ice as far north as King George Island.
