Over the next three days, everyone but Garrett flew out on a plane to return to the United States. Garrett had to stay in camp to help everyone pack their things and to fuel the plane upon its arrival. Only Garrett remained out of the original people. On the last plane that came in to pick up Alexis and two of the foreign workers, Garrett's girlfriend Jackie arrived.
"Why did you want me to come down here?"
"It was going to get really quiet down here."
With no one else using any of the equipment, Garrett set out to remove the rock which he had decided to upon uncovering it. He loaded onto the boat the rocket launcher as well as his AK-47 and the M4 that he had found in Panama City. Garrett then went upstream to the dock, where he stripped the winch cables from two of the jeeps. Jackie unloaded the weapons and put those onto the floor of the bulldozer. Garrett then drove the bulldozer back the several miles to the pyramid. Once there, he took out the cables. He gave one end to Jackie and told her to tie it to the bulldozer's blade while he himself walked up to the rock. There was no good way to tie the cable around, so Garrett wrapped the cable around the rock several times and tied it. Jackie had tied the other end of the cable to the bulldozer, so Garrett told her to turn it on and begin driving the bulldozer away from the pyramid. She began slowly driving away, and Garrett watched the cable become taut. There was a loud grinding noise and the rock slowly began sliding in the direction of the tunnel entrance. Garrett watched as a tunnel heading straight down was exposed from under the rock and ran over to the bulldozer to tell Jackie to stop.
Garrett returned to the central room and untied the cable from around the rock. He told Jackie to move the bulldozer to the entrance of the temple and to come back with a flashlight. As she was off moving the bulldozer, Garrett rigged up the end of the cable to form a simple climbing rig. Once Jackie returned with the flashlight, Garrett took this, turned it on, and jumped down into the opening. He shone the flashlight down the hole, and the beam faded back into darkness about fifty feet down against the smooth rock walls on each side of the tunnel. Garrett began heading down, and stopped again once he had come fifty feet down. He looked down the tunnel, and about thirty feet farther it ended. The light still did not illuminate the floor, though, so Garrett continued to go down. He reached the end of the tunnel down, and now he noticed that the ceiling of the chamber that he was also stone. The flashlight was illuminating one wall next to Garrett, but the other three walls were not visible.
"What is a room larger than one hundred feet long doing underground? What is going on with this pyramid?" Garrett thought.
"What do you see?"
"I don't see anything yet. I don't see a floor; all I see is one wall and the ceiling."
"So it's a large room?"
"I don't know how large. Let me find the floor first."
Garrett continued down along the one wall another fifty feet and looked down again. He could still not see the bottom of the room. He continued down another fifty feet and still could not see a floor. Finally, after going three hundred feet down, Garrett's feet struck a gravel floor.
"I've hit the floor! Now I'm going to go see what's down here!"
Garrett began to walk away from the cable when he realized that there was no echo. He turned back to where a dim light just slightly better than the darkness of the chamber illuminated a small patch of the floor.
"Can you toss down the Kalashnikov rifle?"
"Why?"
"I need to use the scope!"
Garrett had attached a night vision scope to the Kalashnikov rifle from one of the hunting rifles since he preferred an assault rifle and had gained a feel for them from his years in the military. He preferred the Russian AK-47 over the American M16 and M4 due to its larger 7.62mm rounds, which allowed better stopping power. The AK-47 was also a simple gun that could be maintained easily, and it was also very reliable. Garrett's AK-47 clattered to the ground below the tunnel, intact due to its solid construction. Garrett picked up the gun and looked through the scope. He could see two walls, on either side of him, which were each about five hundred feet away. The far wall was still out of range of the night vision scope. However, there was a smaller object in view which appeared to be free standing. This appeared to be a two floor structure about two hundred feet across. This structure was plain, except for what appeared to be a door on one side.
"They didn't have clean doors thousands of years ago. That might be a seal then," Garrett thought.
Garrett walked toward the structure, still looking through the scope. He was two hundred feet away when he saw the door-like feature slide to one side. Several figures exited and appeared to aim firearms at Garrett. They all began to talk in a language that Garrett had never heard before. Garrett dropped to one knee and aimed his weapon back at them. He also held his flashlight in his left hand, which he shone toward the people to get a better view of them on his weapon's sight. They all shielded their eyes, and apparently not used to seeing light.
