Logan Glacier

Logan Glacier is a large glacier straddling the border between Alaska and Canada's Yukon Territory. The ice covers a vast area on Mount Logan's slopes and forms the headwaters of river systems in this remote region.

The glacier was named after Mount Logan, which honors Sir William Edmund Logan, founder of the Geological Survey of Canada. The landscape has been shaped by glacial movement and climate shifts over many decades.

Local indigenous communities of the Yukon and Alaska regions maintain traditional knowledge about the changes in glacial landscapes through generations of observation.

The area is difficult to reach because of its location in a protected national park and at the international border. Most visits require special permits from both countries and specialized mountain equipment.

The ice shows different flow rates on each side of the international border, creating visible patterns when viewed from above. These varying movement speeds result from local topography and snow accumulation on each side.
