Glen Canyon National Recreation Area

Reflection on an Illusion - Pool Canyon, Lake Powell, UT 31-Oct-2011 350PM This canyon housed a pool of water that was sheltered from any wind, making it a perfect mirror for the canyon walls lit by the late afternoon sun. The illusion here is that this view is of the reflection and is upside down, not immediately obvious until you notice the dirt and rocks and grass in the “sky”. When viewed in normal orientation, the reflection is interesting, but lacks the visual challenge and illusion.
