The Canadian Arctic Rift System is a branch of the Mid-Atlantic Ridge that extends 4,800 km (3,000 mi) into the North American continent. It is an incipient structure that diminishes in degree of development northwestward, bifurcates at the head of Baffin Bay and disappears into the Arctic Archipelago.
Baffin Bay (Inuktitut: Saknirutiak Imanga; [4] Greenlandic: Avannaata Imaa; [5] French: Baie de Baffin; [6] Danish: Baffinbugten), [a] located between Baffin Island and the west coast of Greenland, is defined by the International Hydrographic Organization as a marginal sea of the Arctic Ocean. [8]:
Thermal overprinting and deformation from the Paleoproterozoic have been found in these rocks, dating to the Trans-Hudson Orogeny 1.8 billion years ago. The Bylot Supergroup in Baffin Island and Bylot Island is six kilometers thick with a combination of undeformed volcanic, clastic and carbonate rocks deposited during a phase of renewed rifting.
Baffin Bay is the northwestern extension and terminus of the North Atlantic-Labrador Sea rift system that started forming 140 million years ago in the Early Cretaceous epoch. [4] The Labrador Sea started opening 69 million years ago [ 5 ] during the Maastrichtian age but seafloor spreading appears to have ceased by the Oligocene epoch, 30–35 ...

[6] Several ephemeral streams, including San Fernando, Santa Gertrudis and Los Olmos, flow into the bay, but only when it rains.
The highest point in the northern Baffin Mountains is Qiajivik Mountain at 1,963 m (6,440 ft). [6] There are no trees in the Baffin Mountains because they are north of the Arctic tree line. Rocks that compose the Baffin Mountains are primarily deeply dissected granitic rocks. They were covered with ice until about 1500 years ago, and vast parts ...
