Earth from Space - Image Description

STS085-709-039 Williston Lake, British Columbia, Canada August 1997
The elongated, blue-looking feature in the center of the image is Williston Lake, one of the many valley lakes in the Canadian Rocky Mountains of British Columbia. Lighter-colored rivers flow into the lake from the surrounding valleys. Forest clear cuts are apparent as light green patches on the slopes of the mountains and in some of the valleys. Most of the mountain valleys and slopes are covered by dark forests, but the mountain tops are above the tree line and appear gray. Bright, white clouds cover some of the mountain tops.
