The orography of the western coast of Hudson Bay is little known. Most of this coast seems to form a hilly land, consisting generally of granite. Between Wager River and Chesterfield Inlet it rises to a chain of hills of about one thousand feet in height, extending to a plateau farther north. Another chain seems to stretch in a northeasterly direction from Back River to the source of Hayes River. West of Back River Silurian strata prevail. The granite hills form a favorite haunt for the musk ox and reindeer.
Melville Peninsula consists chiefly of a chain of granite hills, sloping down to a Silurian plain in the eastern part of the peninsula. The northeastern part of Baffin Land is formed by a high chain of mountains stretching from Lancaster Sound to Cape Mercy. Long fjords and deep valleys divide them into many groups. Bylot Island, which stands high out of the sea, is separated from the mainland by Pond Bay and Eclipse Sound. The next group stretches from Pond Bay to the fjord of Anaulereë´ling. Farther to the southeast the groups are smaller, and in Home Bay they are separated by wide valleys, particularly near Eχalualuin, a large fjord on the southern side of that bay.
From this fjord an enormous highland, which I named Penny Highland, extends as far as Cumberland Sound, being terminated by the narrow valley of Pangnirtung. The eastern boundary runs through the fjords Maktartudjennaq and Narpaing to Nedluqseaq and Nudlung. In the interior it may extend to about fifteen miles east of Issortuqdjuaq, the most northern fjord of Cumberland Sound. The whole of the vast highland is covered by an ice cap sending forth numerous glaciers in every direction. In Pangnirtung and on Davis Strait they reach the level of the sea.
Penny Highland, which forms the main body of Cumberland Peninsula, has attached to it a few mountain groups of moderate extent: the peninsula of Nudlung and the highland of Eχalualuin and that of Qivitung.
Farther southeast, between the valleys of Pangnirtung and Kingnait-Padli, is situated the highland of Kingnait, with sharp peaks emerging from the ice cap which covers the lower parts of the plateau. The rest of Cumberland Peninsula is formed by the highland of Saumia, which much resembles that of Kingnait. Near Cape Mercy the ice covered highland slopes down to a hilly region, which falls abruptly to the sea.
The southern parts of this range of mountains are composed of gneiss and granite. It may be that Silurian strata occur in some places, but they have not yet been found anywhere in situ. The northern parts are too imperfectly known to enable us to form an idea of their geological character.
The mountains just described slope down to a hilly region, which farther to the west levels off to a plain. The hills are composed of granite, the plains of Silurian limestone, which extends from Prince Regent Inlet to the head of Frobisher Bay.
The peninsula between Cumberland Sound and Frobisher Bay is formed by a plateau, which slopes down gradually to the northwest. It is drained by a great river flowing into Auqardneling, a fjord on the western shore of Cumberland Sound. Near Lake Nettilling the country is very low, the level of the lake being only forty feet above that of the sea. Here the watershed between Cumberland Sound and Fox Basin closely approaches the eastern shore, coming within five miles of the head of Nettilling Fjord. It is formed by a narrow neck of land about a quarter of a mile wide and sixty-five feet above the level of the sea.
From Eskimo reports I conclude that the plateau of Nugumiut, as we may call the peninsula between Frobisher Bay and Cumberland Sound, is comparatively level. Only a single mountain south of Qasigidjen (Bear Sound) rises into the region of eternal snow.
The peninsula between Frobisher Bay and Hudson Strait is formed by a granite highland, the Meta Incognita of Queen Elizabeth. It is covered with ice and sends a few glaciers into the sea. Farther west, near Lesseps Bay and White Bear Sound, the country becomes lower. The narrow isthmus leading from Hudson Strait to Amaqdjuaq cannot be very high, as the Eskimo carry their kayaks to the lake, which I believe is about two hundred feet above the level of the sea.
