Geography

It is a broad channel that runs roughly from northwest to southeast between the mouth of the Inglefield Fjord and Baffin Bay. It is 51.8 km wide between Cape Robertson and Hakluyt Island and its minimum width is 14 km.[2]

The Murchison Sound separates Prudhoe Land and Piulip Nuna —part of the Greenland mainland— to the north from Kiatak (Northumberland Island) and Qeqertarsuaq (Herbert Island) to the south with Cape Cleveland on the northern shore. On the south side of the islands the Whale Sound leads from the Baffin Bay to the Inglefield Fjord.[3]

The Robertson Fjord and the MacCormick Fjord have their mouths on the northern side of the sound.

gollark: Oh, I already deployed it.
gollark: We memetically bombard this with the idea that the current situation is not optimal, and THEN genericize them.
gollark: Of course.
gollark: As a Go developer, you have surely encountered at some point something using the `container` package, containing things like `container/ring` (ring buffers), `container/list` (doubly linked list), and `container/heap` (heaps, somehow). You may also have noticed that use of these APIs requires `interface{}`uous type casting. As a Go developer you almost certainly do not care about the boilerplate, but know that this makes your code mildly slower, which you ARE to care about.
