The northern boundary of the Southern Winter Seasonal Zone
is:
the rhumb line from the east coast of the American continent
at Cape Tres Puntas to the point latitude 34° S, longitude 50°
W, thence the parallel of latitude 34° S to longitude 16°
E, thence the rhumb line to the point latitude 36° S, longitude
20° E, thence the rhumb line to the point latitude 34° S,
longitude 30° E, thence along the rhumb line to the point latitude
35°30' S, longitude 118° E, and thence the rhumb line to Cape
Grim on the north-west coast of Tasmania; thence along the north and
east coasts of Tasmania to the southernmost point of Bruny Island,
thence the rhumb line to Black Rock Point on Stewart Island, thence
the rhumb line to the point latitude 47° S, longitude 170°
E, thence along the rhumb line to the point latitude 33° S, longitude
170° W, and thence the parallel of latitude 33° S to the point
latitude 33° S, longitude 79° W, thence the rhumb line to
the point latitude 41° S, longitude 75° W, thence the rhumb
line to Punta Corona lighthouse on Chiloe Island, latitude 41°47'
S, longitude 73°53' W, thence along the north, east and south
coasts of Chiloe Island to the point latitude 43°20' S, longitude
74°20' W, and thence the meridian of longitude 74°20' W to
the parallel of latitude 45°45' S, including the inner zone of
Chiloe channels from the meridian 74°20' W to the east.
