Five men were brought back to safety Sunday night by emergency crews in Virginia after being trapped since the morning, CBS affiliate WJHL-TV reports. The group, between the ages of 34 and 59-years-old, got stuck in a cave in southwest Virginia, about 180 miles east of Roanoke.

Russell County EMA Director Jess Powers told WJHL-TV that six men entered Cyclops Cave on Saturday with an intention of camping. One man was able to escape and alert authorities to the situation. The rescue began at 10:30 a.m. Sunday morning and wrapped up around 6 p.m.

Apparently heavy rainfall hit the cave once they became trapped, making it more difficult for then trapped men to escape on their own. At the time rescuers arrived, the men were suffering from fatigue and hypothermia. Officials said the men were 120 feet deep and did not come equipped with proper climbing gear.

"When you stop moving and aren't able to get up and move around or you run out of energy, that can cause problems with hypothermia," Billy Chrimes of the Virginia Department of Emergency Management said.

According to WJHL-TV, The American Red Cross from Bristol, Cleveland Life Saving Crew, Lebanon Fire Department and Cleveland Fire Department were on scene, which has been confirmed to be a private property.

WJHL-TV spoke with property owner Frankie Smith who said this is the first time someone has gotten stuck in the cave, which is 2 miles long, and that the men did not have permission to enter.
