what rim is the grand canyon observation deck
Grand Canyon observation deck reaches dizzying heights. A whole new way of scaring yourself stupid opened above the Grand Canyon in Arizona yesterday. It's called a Skywalk and a million visitors a year are expected to tread its glass walkway, look down three-quarters of a mile, and feel like they've stepped off the edge of the world. The horseshoe-shaped observation deck extends 70ft beyond land and there are no reassuring supports below.
