Of all the hazards that can worry Utah's hikers, "marooned on an iceberg" is not usually high on the list.

But that's what happened (sort of) to a group of hikers who found themselves stranded overnight after a hail-laden flash flood left their boat blocked by a foot-thick layer of ice in — wait for it — Lake Powell's Iceberg Canyon

Nick Woolley, of Salt Lake City, caught the bizarre-looking ice floes on film as they churned around his campsite Saturday during an outing with his wife and two friends. They had been hiking in the upper end of the canyon when the storm hit.

"When we saw the brown wall of water coming down the canyon we freaked out a bit," Woolley confessed.

But the group had picked a campsite protected by a bend in the canyon and with easy access to higher ground, allowing Woolley to shoot some very cool footage of a raging, tawny river coated in white hail.

The hail accumulated in the canyon, forming a table of ice "a foot thick and hundreds of yards across," Woolley recounted.

"We couldn't get out of the canyon the rest of the night," Woolley said. "It was packed with ice."

Meanwhile, the water temperature in Iceberg Canyon plunged from 74 degrees to 34 degrees.
