Sermillik Glacier

This glacier gives its name to the Sermillik National Park in which it is located, and it is a prominent feature when viewed from the town of Pond Inlet on the Baffin Island side of Eclipse Sound. The views here are all taken of the terminal area from a helicopter. This is one of the larger glaciers on the island, with a length of 30 km and a width of 2 to 3.5 km. It terminates a short distance from the sea on a flat braided proglacial area. Supplied with ice from multiple accumulation basins, the tongue is dominated by longitudinal foliation formed at the confluence of each basin. This structure is clearly visible in the lower part of the glacier, where it is gently folded. The margins of the glacier comprise several ice-cored lateral moraines, indicating sporadic recession in recent decades. The proglacial area is of glaciofluvial sand and gravel, and is partly covered by Aufeis.

The snout area in profile with braide rivers and lateral moraines. The low angle profile is typical of a rapidly receding ice margin.
Sermillik Glacier
A substantial unnamed side glacier, on the east margin near the snout, was formerly a tributary. It has down-wasted even more that Sermillik Glacier itself, as indicated by the trim-lines.

The true right-hand (west) margin showing a prominent medial moraine. The sinuous nature (emphasised by this foreshortened view) is the result of longitudinal compression.
Sermillik Glacier
The lateral moraine complex at the true right-hand margin of the glacier. The series of weakly defined ridges indicates pauses in the general glacier recession from the Little Ice Age limit.

Three braided river systems converge near the right-hand margin of the glacier. The middle one is associated with Stagnation and Fountain glaciers.

Substantial glacier recession is evident in this aerial view of an unnamed glacier between Stagnation and Sermillik glaciers.
