Devastation And Cleanup After Colorado Flooding

Officials in Colorado are on a frantic rescue mission, searching for hundreds still missing since flash floods crippled parts of the state last week.

In some neighborhoods, residents returned home to find they'd lost everything. CNN's George Howell reports.

New images emerged overnight with choppers taking to the sky, evacuating at least 100 people.

Nick Christensen with the Larimer County Sheriff's office said, "Some areas in Larimer County experienced a 100 year flood...others experienced a 1000 year flood, something that would only happen every 1000 years."

Returning to a devastated community, residents in Longmont are seeing their homes for the first time since Thursday and discovering they're no longer habitable.

Resident Jeff Larsen said, "It's ruined, our basement is gone. It stinks so bad in there you can barely stand it."

Thick mud and water moved through Lyons, shifting entire homes from their foundation.

One woman, Kelly Hunt, was unable to reach her home on the other side of the river. She was in utter disbelief that it was picked up and moved several feet.

Hunt said, "Today is our first day up here since we've been evacuated, and I feel like it's worse than I thought it would be. We lost absolutely everything we own."
