Three Arkansas State University students were rescued Thursday after getting lost in a cave for more than 30 hours.
Wednesday morning, Casey Sherwood and two friends from Japan went into Blowing Cave to go spelunking, reported NBC affiliate KARK.
They couldn't find their destination in the cave and couldn't find their way out, so they spent the night there, periodically calling for help.
After all that time, rescuers finally tracked them down.
"We did our little routine 'help,' and finally we heard just a tiny little voice off in the distance," Sherwood says.
