Another image of Lake Oesa, along with one of the few trees able to brave the extreme conditions here. The high elevation and cloudy weather caused the mountain peaks to unfortunately be socked in at the lake, but this helped lend a moody atmosphere to this chilly landscape.
I believe the mountain visible here is called Glacier Peak. To the left of this image is Mount Lefroy, and not far from that is Abbott Pass. Very experienced mountaineers can climb the loose scree to the pass from Lake Oesa, and then descend the other side of the Continental Divide to Lake Louise.
