 Park Ranger and Custer County Sheriff's responded first and were able to hear the lost, but with the echo of the rock obstructions, it made it difficult for the lost to follow the law enforcement's audible calls or for law enforcement to pinpoint their location. Custer County Search and Rescue arrived and climbed down near the tunnels and were able to find the lost a short time later. They were wet, thirsty, and cold as a storm had just rolled through the area and needed a little help climbing back out.
