The deck is anchored deep into a limestone cliff. As people walk across it, the glass layers creak and the deck wobbles almost imperceptibly. To one side, the Colorado river appears as a slim, pea-green ribbon. To the other is a triangular dip in the canyon's ridge, known as "Eagle Point" because it looks like a bird with outstretched wings.
When the wind blows, only the most daring visitors resist grabbing the steel rail to steady their knees.
The tribe will include access to the deck in a variety of tour packages ranging from $49.95 to $199.00. They'll allow up to 120 people at a time to look down to the canyon floor more than 4,000 feet below, a vantage point more than twice as high as the world's tallest buildings.
I certainly wouldn't do it with 119 other people out there with me, that's for sure.
