“Which do you prefer?” she said. “Would you rather dig down below our feet to establish that it’s paved or climb up there and dig to see if the hill is a building that was overgrown by the jungle?”
“If we’re way up there, we might be able to see for a distance,” he said.
“That’s what I think too,” she said. “It might be nice to look above the treetops, for a change.”
They left their packs, took their machetes and folding shovels, and climbed. The hill they chose was the center one on the right side. It appeared to be the highest. The hill was steep, rising to a height of about a hundred twenty-five feet, and its slopes were thick with plants and small trees, which they used as handholds.
When they reached the apex, Sam unfolded the shovel and began to dig. After about four shovelfuls, his blade hit stone. He used his machete to test a few spots nearby and the sound was the same. Remi walked a few yards to get past a thicket of saplings, growing on the top of the building. “Don’t get lost,” Sam said.
“Come here,” she said. “You’ve got to see this.”
He took the machete and shovel with him and went through the thicket to find Remi, looking out over the tops of the jungle trees. From here, the canopy looked solid, but there were a few places where it was sparse. She pointed down at the level area they had left. “It’s like a wide road. It starts here and runs between the hills in a straight line. But it runs only a few hundred yards.”
“And over there,” Sam said, “another flat strip comes in at an angle and meets it.”
“There’s another over there,” said Remi. “Five—no, six—strips, coming in from six directions to meet at one spot.”
“It looks like an asterisk with a high wall circling the center,” Sam said.
“You could fly over this area a hundred times and not really see it,” Remi said. “The trees make everything seem natural. The shapes are rounded off, but I’ll bet this hill we’re standing on is a pyramid.”
“It’s something big anyway,” Sam said. “Well, I guess we know where we have to go.”
“Of course,” she said. “The place where the roads meet.”
When Sam and Remi reached the bottom of the steep hill, Remi said, “This is creepy.”
“What’s creepy?”
“You know they’re not hills, they’re huge buildings covered with dirt and plants. And these trees around us would be the only things that aren’t creepy except that they’re growing in the middle of this road. I feel like the people who lived here are watching us.”
“Trust me, they’re not.” He looked over his shoulder. “Nope. Not one ghost. But, just in case, let’s leave the Jeep here.”
As they walked, Remi said, “Look at those trees. The cover was all pretty much the same until we got here. Now look. The trees are all in a straight line.”
Sam stood beside her and sighted along the flat strip
, where trees of all sizes and many species all ran along the center in a line. He stopped, shrugged off his pack, and began to dig a hole in line with the trees. The dirt was a rich, composted loam that came up easily. Shortly, he had a hole three feet wide and about three feet deep. “Take a look,” he said, and stepped out of the hole.
Remi jumped in, looked down, and used her machete to probe the surface. “It’s V-shaped and has a stone lining. It looks like an irrigation ditch.”
Sam looked around him, turning his body slowly. “I think it might be something else.”
“What?”
“Think back. Dave said that whatever else was going on in the Mayan world during the late classic period, it was made worse by droughts—two hundred years of them at least.”
“What do you think this was?”
“I think this flat space wasn’t a road. The Mayans had no wheeled carts, or tame animals to pull them, so why make it fifty paces wide? And it doesn’t go anywhere. It looks like a plaza, except there are six of them in all directions. I think this place was designed to collect rainwater.”
“Of course,” she said. “Both sides have a subtle slope down to the groove in the center and the groove would direct the water where they wanted it.”
“And that would explain why there are six strips leading inward from all sides. The place where they meet is the catch basin,” Sam said. “The six strips aren’t roads. They’re for catching rain and keeping it from washing away and sinking into the ground.”
“Let’s go see if we’re right,” said Remi. They hurried along the strip toward the spot where all six converged. At times, the brush and saplings came together to make their progress difficult. Here and there, the surface of the strip was bare even of leaves, cleared by some inundation during the rainy season.
At last, they came to the end. The strip ran to the foot of an ancient stone wall about fifteen feet high. The V-shaped ditch led to an opening in the bottom of the wall, where there was a hole about ten inches wide. They walked around the circular wall and saw that each of the other five strips met the wall in the same way, bringing the water in through small openings at its foot. They found that the wall was not a circle with a gap in it for a door or gate. It was a spiral, so that the circular wall stretched for a full three hundred sixty degrees, and then continued ten degrees past the beginning spot so it overlapped for about ten feet to form a narrow, curved corridor ending in an entrance. Sam and Remi sidestepped along the corridor and found themselves inside the circular wall. In the center was a pool of water.
