The Emerald lake, Canada , by khenshikai

Joffre Lakes Provincial Park has opportunities for hiking, camping, mountaineering, wildlife viewing, and fishing. A highlight of the park is the turquoise blue waters of Lower, Middle and Upper Joffre lakes, all three of which are located along the trail, and each more stunning than the last. Their striking, saturated blue colour is caused by “rockflour” – or glacial silt – that is suspended in the water and reflects green and blue wavelengths of sunlight.
