Lyons, Colo. • By truck and helicopter, thousands of people stranded by floodwaters came down from the Colorado Rockies on Friday, two days after seemingly endless rain turned normally scenic rivers and creeks into coffee-colored rapids that wrecked scores of roads and wiped out neighborhoods.
Authorities aimed to evacuate 2,500 people from the isolated mountain community of Lyons by the end of the day, either by National Guard convoys or airlifts.
One was Mary Hemme, 62, who displayed a pair of purple socks as she sat outside the Lifebridge Christian Church in Longmont. They're a memento of the more than 30 hours she spent in an elementary school in the flood-stricken mountain town of Lyons. Many evacuees eventually rescued by National Guard trucks got socks because most of them had wet feet, Hemme said.
She recalled a frantic climb uphill after sirens blared at 2:30 a.m. Wednesday.
"Mary, we have to go, this place is flooding," she recalled her friend Vincent saying as they clambered out of a trailer. They stepped outside their trailer and into rushing water that nearly reached their knees.Others were less fortunate. The body of a woman who had been swept away was found Friday near Boulder, raising the death toll to four.
National Guard troops aided by a break in the weather started airlifting 295 residents from the small community of Jamestown, which has been cut off and without power or water for more than a day.
Dean Hollenbaugh, 79, decided to take one of the helicopters after officials warned electricity and water could be disrupted for weeks.
"Essentially, what they were threatening us with is 'if you stay here, you may be here for a month,'" Hollenbaugh said as he waited for his son to pick him up from the Boulder airport. "I felt I was OK. I mean I've camped in the mountains for a week at a time."
Airlifts also were taking place to the east in Larimer County for people with special medical needs.
The relentless rush of water from higher ground turned towns into muddy swamps, and the rain returned Friday afternoon after a brief lull. In at least one community, pressure from the descending water caused sewer grates to erupt into huge black geysers.
Damage assessments were on hold, with many roads impassable and the rain expected to continue.
"This one's going to bring us to our knees," said Tom Simmons, president and co-owner of Crating Technologies, a Longmont packing service that had its warehouse inundated. "It's hoping against hope. We're out of business for a long time."
Most of the 90 miles of Interstate 25 from Denver to Cheyenne, Wyo., was closed Friday because of flooding from the St. Vrain, Poudre and Big Thompson rivers, transportation officials said.
Hundreds of people were forced to seek emergency shelter up and down Colorado's heavily populated Front Range, which has received more than 15 inches of rain this week, according to the National Weather Service.
That's about half the amount of precipitation that normally falls in the foothills near Boulder during an entire year.
Boulder County officials said 80 people were unaccounted for Friday. But, they noted, that doesn't necessarily mean they're missing.
"It means we haven't heard back from them," county spokesman James Burrus said.
One person was killed when a structure in Jamestown collapsed. Another man drowned in floodwaters north of Boulder while trying to help the woman whose body was found Friday.
To the south, Colorado Springs officers conducting flood patrols found the body of a 54-year-man in a creek.
