Emerald Lake, Mountain lake in Yukon, Canada

Emerald Lake is a shallow, landlocked lake on the South Klondike Highway at kilometre 117.5 from Skagway, Alaska, about 60 km from Whitehorse. It lies at 705 m above sea level and gets its green colour from light reflecting off white marl, a mix of clay and calcium carbonate, on its bed. Another lake of similar colour, Spirit Lake, lies 200 m to the south across the highway.

The lake basin was carved by glacial activity roughly 14,000 years ago during the last Ice Age. Glaciers shaped the surrounding terrain and established the geological conditions that create the water's distinctive appearance today.

The lake is also known as Blue Lake, and Spirit Lake lies about 200 metres south across the South Klondike Highway, with water of a similar colour. The lake sits at an average elevation of 705 metres and has no outlet, so its water level depends on inflow and evaporation.

The lake can be reached via the Klondike Highway and offers several viewpoints along the route for observation and photography. These spots provide different angles to experience and capture the water from various perspectives.
