According to Fox News:
A California Highway Patrol helicopter crew spotted Dominguez atop a small bridge and landed nearby, sinking into 2 feet of snow, flight officer David White said. The family had taken shelter in a culvert beneath the bridge and stomped "help" in the snow, White said.David White is one of the thousands of First Responders nationwide who are there when we need them. Because of his bravery and dedication, the Dominguez family is safe and home for Christmas.
White said it was the last opportunity for the helicopter, with snow falling heavily as it descended.
Frederick Dominguez said huddling with his three children in a culvert for three days to keep warm made him even more grateful of what is important in life ...
... "faith, family, friends."
