Faith-based groups are among those mobilizing to help victims of the massive flooding in Colorado. As flood waters began to recede this week, the magnitude of the devastation started coming into focus, although many areas are still inaccessible. State officials estimated that more than 19,000 homes were damaged or destroyed. Churches set up shelters for thousands of people who were evacuated. Religious groups are providing emergency aid, assessing long-term needs, and calling for volunteers.
