The Carlson Dairy farm in Pennock, Minnesota, has been in the family since the 1800s.
But the Carlsons have never seen anything like what happened Sunday morning.
Chad Carlson and a few employees were working at about 7 a.m. when Carlson saw the sky get dark to the west as he went into one of their barns.
Shortly after, he suddenly felt the roof rip off and felt powerful winds whipping through the building. In just minutes, about 10 animals were injured and nearly all of the farm's buildings were damaged, some of them almost completely leveled.
The family was overwhelmed and not sure how to start cleaning up, but then hundreds of people came to help, volunteering after seeing a Facebook post about the damage.
Carlson says he can't believe the kindness of strangers who dropped everything to lend a hand.
"Probably 15 percent of the people here that I don't know and they're just here to help," Carlson says. "And they might not even know where to help, but they're jumping in, helping. So that's pretty awesome."
Volunteers from as far away as Worthington are temporarily taking in the Carlson's cows, providing food, and cleaning up debris.
