One if by land, two if by...air? A massive flood that began in Colorado Wednesday continued into Friday as authorities sent in helicopters to rescue stranded residents of the small mountain village of Jamestown. The town, which lies in a canyon, was isolated by flooding that left no land-based way for its remaining 295 citizens to evacuate. Meanwhile, the National Guard sent trucks to Lyons, a city to the northeast, with more airlifts expected to follow. Food and clean water were dropped to residents still awaiting rescue as the flood rapidly accelerated into parts of an area the size of Connecticut. The rescues continue into Saturday.
