From the main trail you cannot see over that ridge to view the lake itself. The ridge is the end moraine of the glacier above the lake. It marks the limit of the glacier's latest advance, which occurred about 100 years ago. Now that the glacier has melted back, this natural dam impounds the meltwater from the glacier. In similar fashion, the water of the Weasel River is totally opaque.
Glaciers crush rock into extremely fine particles called glacial flour.
When these tiny particles are suspended in water, the mixture is called glacial milk. At any point on the line, there is one day of near total sunshine on June 21 and one of near total darkness on December 21. In the past, Inuit climbed past these falls to hunt caribou in the valleys beyond. This regal mountain is named after the Norse god of thunder as a tribute to its power. Summit Lake - Tasiruluk marks the height of land in Akshayuk Pass.
