Llewellyn Glacier, Glacier in British Columbia, Canada

Llewellyn Glacier is a large glacier in the Boundary Ranges of British Columbia that spans several kilometers across the landscape. It channels meltwater from the Juneau Icefield into Atlin Lake, connecting the high mountain terrain with the lake system below.

The glacier was first scientifically documented in the early 1900s when researchers recorded its appearance and movements. Those early observations form the foundation for tracking how it has changed over more than a century.

The glacier sits within Atlin Provincial Park, where it shapes the landscape that hikers and nature observers explore. Visitors can see how glacial melt influences the surrounding waters and the changing terrain around them.

Visitors can reach the glacier area from Llewellyn Inlet Campground, which sits on the shore of the inlet. Summer offers the best conditions for exploring, as the weather is more stable and access routes are more open.

On 6 June 2018 a kilometre-sized piece of the glacier's narrow tongue broke off and fell into Atlin Lake. The Llewellyn is the second-largest glacier of the Juneau Icefield, and its meltwater feeds the source of the Yukon River, whose name means "river of white water" in Gwich'in.
