''There are other Adams Islands, including
one more sub-antarctic island. See
Adams Island for other meanings.''
'Adams Island' is the part of
Auckland Islands archipelago. The southern end of the island broadens to a width of 26 kilometres. Here, a narrow channel known as Carnley Harbour (on some maps the Adams Straits) separates the main island from the roughly triangular Adams Island (area approximately 100 km²), which is even more mountainous, reaching a height of 660 m with Mount Dick. The channel is the remains of the crater of an extinct
volcano, and Adams Island and the southern part of the main island form the crater rim.
