Easton resident Dough Mackie told Fox56 he let the dad and his kids go ahead of him on the Sullivan Express lift around 3:30 p.m.
Mackie was two cars away when the lift suddenly stopped, and their chair started to sway. Then, it dropped, he told the outlet:
“My jaw dropped, this kid his jaw dropped," Mackie said. "And then we heard the screaming and then the two little kids were loud, I heard the little girl, I heard her."
The family was taken to a local hospital with serious injuries, reports say.
Camelback Mountain released a statement Tuesday regarding the incident:
It is unknown when the Sullivan Express lift will reopen.
