Corrie Lake is the surreal looking lake that can be seen across the valley from Whistler Mountain.  While hiking the High Note trail along Whistler Mountain it slowly comes into view, seemingly hanging in the forest on an otherwise steep sided, broad mountain.  The broad mountain that Corrie Lake sits within is called Corrie Ridge, which extend from Corrie Peak to Gentian Ridge.  The ridge is named Corrie Ridge because Corrie Peak is the highest peak along the ridge.
