Set in a hanging valley backdropped by the majestic mountains of the Continental Divide, this beautiful glacier-fed lake, with the stately chateau near its shore. Visible at the far end, the Victoria Glacier once stretched to the site of the chateau. The 2km/1.2mi-long, .5km/.3mi-wide tarn (maximum depth 75m/246ft) was created when this glacier retreated, leaving enough morainal debris to serve as a dam. The chateau is actually built on the moraine. Fed by glacial meltwater draining off the surrounding peaks, the lake (maximum temperature 4°C/40°F) changes color with light conditions and as the summer progresses. Known as glacial flour, fine powdery silt suspended in the water refracts the green rays of the spectrum and emits hues ranging from bluish-green to emerald.
