GRANITE FALLS, Wash. — A video posted to YouTube shows an ice cave roof collapsing at the Big Four Ice Caves in Granite Falls, Washington.

Sara Soleimani, who shared the video with KIRO 7, says people were inside the cave during the collapse on Sunday, but they were not under the ice when it fell.

This ice cave collapse is different than the one on Monday that killed one person and injured five others. Click here for updates on that story.

In the video from Sunday, people walk out of the cave after the collapse; one shaking his head as others observed the fallen ice.

"You could [have been] killed," a woman either shooting or near the camera said.

Many signs around the cave tells hikers to not go inside it.

KIRO 7 reached out to U.S. Forest Service officials, who said they did not hear of the collapse before the video was posted.
