Hearing what they thought was the crack of thunder just minutes before rocks began to rain from above.  Visitors had been resting just below Landscape Arch minutes before tons of rock fell from the worlds widest natural arch.  Thankfully they moved in time and no one was hurt on that September day in 1991.

Here, Sherry rests after we hiked up to see this one-of-a-kind geologic wonder in Arches National Park in Utah.  The Navajo Sandstone of this area is sculpted by wind, rain and variations of the weather, year after year.  I wonder how long it will be before it disappears forever?
