SEATTLE (AP) — The climbers who were stranded for days near the top of Mount Rainier have been released from a Seattle hospital.

All four men were released Thursday night after being treated for injuries including frostbite and altitude sickness.

Yevgeniy Krasnitskiy of Portland, Oregon, described the harrowing conditions they faced after one of them became ill and unexpected winds ripped through their camp, causing them to lose some of their gear.

They called 911 Monday afternoon but Mount Rainier National Park officials say stormy weather hampered the first five attempts at a helicopter rescue.

It wasn’t until Thursday morning that a crew could land and lift the climbers off the mountain.

Krasnitskiy was quoted as saying that the lesson he’s learned is, “Don’t mess with Rainier.”
