Bellot Strait (Ikirahaq) separates the peninsula from Somerset Island to the north. Babbage Bay is on the east coast, as is Abernethy Bay, just to the south. The community of
Taloyoak lies in the far south and is the peninsula's only significant population centre. Paisley Bay is on the west coast, as is Wrottesley Inlet (between Paisley Bay and Bellot Strait). Prior to the detachment of
Nunavut in 1999, the Boothia Peninsula and the nearby
Melville Peninsula were the only parts of mainland Canada that belonged to the
District of Franklin in the then
Northwest Territories. The balance of the District of Franklin was all situated within the
Arctic Archipelago. ==Geology and paleontology==
