Nugget Falls, Waterfall at Mendenhall Lake in Juneau, United States.

Nugget Falls is a two-tiered waterfall on the edge of Mendenhall Lake, near Juneau in southeast Alaska. The water falls over dark rock faces before reaching the lake, which lies at the foot of the Mendenhall Glacier.

Nugget Falls took its current form as the Mendenhall Glacier pulled back over recent decades, exposing the rock face and allowing meltwater from the smaller Nugget Glacier above to fall into the newly formed lake. Before the glacier retreated, the water ran over ice rather than open rock.

Nugget Falls is reached by a trail from the Mendenhall Glacier Visitor Center, and the gravel bar at its base is a stopping point for watching the meltwater of Nugget Creek meet Mendenhall Lake. Bald eagles are often seen perched on rocks near the shore. The falls lie in the Tongass National Forest, land of the Tlingit, whose presence in the Juneau area long predates the glacier's retreat.

A well-marked trail from the Mendenhall Visitor Center leads to a gravel area at the base of the falls in about 30 to 45 minutes of easy walking. The ground near the water can be slippery when wet, so sturdy footwear is a good idea.

The water carries fine glacial particles that give it a milky blue color, most visible on overcast days when the light is flat. On calm days, chunks of ice that have broken off from Mendenhall Glacier drift close to the falls, sometimes right up to the gravel shore where visitors stand.
