Water sampling in Kluane National Park and Reserve.

A Parks Canada biologist conducts water quality sampling in the Dezadeash River, Kluane National Park and Reserve, Yukon Territory. The biologist smiles warmly as she leans over the guard rail of a highway bridge, holding a round water sampling device attached to a rope. Under the bridge, a wide river flows several metres below. The background shows a grassy riverbank with a stand of tall green shrubs. Steep snow-kissed mountains rise in the distance above a wide forested valley under a grey overcast sky.
