Located in the southeast corner of Rocky Mountain National Park, Wild Basin is drained by the North St Vrain Creek and its tributaries. Numerous alpine lakes dot the area, with Thunder and Bluebird among the most dramatic in the park. Mountain peaks reaching over 13000 feet above sea level form a rock boundary on the north, south, and west sides of this high mountain valley. Bighorn sheep, mountain lions, bears, elk, mule deer and many smaller mammals and birds live in the area. - NPS
