A resort spokesman said preliminary findings made by state inspectors point to the 40-mile an hour winds that were blowing at the time.
Skiers are still shaken up by the accident.
"We were about six chairs up from where it fell and my mom, she fell off and she's at the hospital right now with a cracked rib," said witness Tabor van Risen. "It was pretty scary because we were up there for a really long time, so we didn't want anything else to happen."
Six of the eight injured skiers are now out of the hospital.
