Emergency management officials say six men entered Cyclops Cave near Cleveland and had planned to camp overnight Saturday until conditions worsened because of the rains, which also made it difficult for them to get out.
A 22-year-old man managed to get out about 2 a.m. Sunday and reported that the others were exhausted and suffering from hypothermia.
Virginia Department of Emergency Management search-and-rescue coordinator Billy Chrimes says state and local crews were working Sunday to plan and execute rescue efforts.
As of 6:30 p.m., two of the men had been rescued.
The cave measures roughly 7 miles (11 kilometers) long, but Chrimes says the men weren’t very far into it when they became trapped.
