On their way back, Robert noticed one of the rumored side passages, known for its complex and narrow layout. This part of the cave was mostly unmapped, but Robert pressed on. The passage was about 150 feet long, winding, and difficult to navigate. It required a special technique to maneuver through the cramped Limestone tunnels. He had to move first with his arms, then his shoulders, and finally his legs. As Robert reached the first dangerous section, known as the keyhole formation, he made a crucial mistake. He squeezed through head first, unaware that he wouldn’t be able to reverse with his legs first. Experts always advise going leg first in unknown areas to avoid getting trapped. Already tired, Robert tried to push through the narrow opening, exhaling all the air from his lungs. He soon realized he couldn’t go forward, and his torso got tightly wedged between the rock walls. His arms were pinned, one beneath him and the other pushed back by a rock outcropping. Despite his efforts to push back, gravity pulled him deeper and he found himself trapped with his face above the muddy floor of the cave. Panic set in, and Robert called out for Richard’s help.
