Air crews rescued more than 100 people in Larimer County Monday. Once the evacuations end, officials said it could take weeks or even months to search through flood-ravaged areas looking for people who died.
In the mountain towns, major roads were washed away or covered by mud and rock slides. Hamlets like Glen Haven were reduced to debris and key infrastructure like gas lines and sewers systems were destroyed.
Hundreds of homes around Estes Park, next to Rocky Mountain National Park, could be unreachable and uninhabitable for up to a year, town administrator Frank Lancaster said.
The town of Lyons was almost completely abandoned. Emergency crews gave the few remaining residents, mostly wandering Main Street looking for status updates, a final warning to leave.
Most of Lyons' trailer parks were completely destroyed. One angry man was throwing his possessions one by one into the river rushing along one side of his trailer on Sunday, watching the brown water carry them away while he drank a beer.
