Part of the mountains known as Main Range contains mainland Australia's five glacial lakes.
The largest of these lakes is Blue Lake, one of the headwaters of the Snowy River.
The other four glacial lakes are Lake Albina, Lake Cootapatamba, Club Lake and Headley Tarn.

During the last ice age, which peaked about 20,000 years ago in the Pleistocene epoch, the highest peaks of the main range near Mount Kosciuszko experienced a climate which favoured the formation of glaciers, evidence of which can still be seen today.
Cirques moraines, tarn lakes, roche moutonnées and other glacial features can all be seen in the area.
Lake Cootapatamba, which was formed by an ice spilling from Mount Kosciuszko's southern flank, is the highest lake on the Australian mainland.
Lake Albina, Club Lake, Blue Lake, and Hedley Tarn also have glacial origins.

There is some disagreement as to exactly how widespread Pleistocene glaciation was on the main range, and little or no evidence from earlier glacial periods exists.
The 'David Moraine', a one kilometre long ridge running across Spencers Creek valley seems to indicate a larger glacier existed in this area at some time, however the glacial origin of this feature is disputed.

There is evidence of periglacial activity in the area.
Solifluction appears to have created terraces on the north west flank of Mount Northcote.
 Frost heave is also a significant agent of soil erosion in the Kosciuszko Area.
