"I don't know what to tell you. If an animal ripped up one of the hoses, we'd see water flowing back here. Only that's not the case."
"Then there's just one explanation. The marsh must be receiving water from an underground source faster than we can pump it out."
"That's what I figured. The cave river might connect to it."
"Maybe. But limestone bedrock absorbs moisture like a sponge. That's why Mexico's got so many sinkholes. They call them cenotes. Basically, rainwater filters through the limestone and carves out underground caverns. Eventually, the top layer of limestone breaks away and you've got an underground pool." I frowned. "In other words, the river should be leaking down, not to the side."
"But it's not ordinary limestone. According to Beverly, it contains rare metals."
"Did someone say my name?" Beverly crossed out of the marsh and walked to the box.
"Yeah. I was talking about those metals you found," Graham said. "Any chance they'd help the bedrock resist moisture?"
"I don't know." Her voice pulsed with excitement. "And right now, I don't care."
We stared at her.
"I was helping the Maneros filter the debris out of the water. I found a couple of interesting rocks, so I took them back to camp. You're not going to believe this." She took a deep breath. "They're shatter cones and tektites."
Graham and I looked at each other. "What the hell are shatter cones and tektites?" he asked.
"Shatter cones are rocks with thin grooves carved out of them. They look like horsetails. And tektites are small dark objects made of natural glass. They form during high-temperature events. Hunahpu must've dug real deep to get bedrock for his pyramid."
I rubbed my jaw. "What kind of high temperature event?"
"If it was just the tektite, I'd say a volcano. But the shatter cones are a dead giveaway. They only form during underground nuclear explosions or," she grinned, "impact events."
"So, this isn't a canyon," I said slowly. "It's a …"
"Crater," she said, finishing my thought. "Hard to believe, right? But it makes perfect sense. A small meteor must've entered Earth's atmosphere thousands or even millions of years ago. It struck these mountains and drove a hole straight into the limestone."
I nodded slowly. "That would explain the shape of this place, not to mention the sheer walls."
"It would also explain the extinct radioisotopes."
"They travel on meteors?"
"Not usually," she replied. "But that's because most meteors come from this solar system. I'm thinking the meteor that formed this crater might've been extrasolar in nature."
"There's just one problem." I studied the marsh. "The jungle slopes this way. But the marsh itself is flat. If a meteor really did hit here, wouldn't you expect it to keep sloping into a basin?"
"I suppose so."
My lips tightened. I strode forward.
"Where are you going?" Graham called out.
I didn't answer him. Instead, I grabbed a shovel and walked to the eastern edge of the marsh, right where the slope vanished. I took a few seconds to mark out a large circle with my boot. Then I thrust my shovel into the dirt and tossed heavy mud to the side.
The rain picked up speed, pelting my head and shoulders. Beverly and Graham retrieved shovels and joined me in the marsh. Silently, we dug into the soil.
Five minutes passed. Then ten minutes. Fifteen minutes. Gradually, Dora and Renau wandered toward us. Miranda and Tum did the same.
Clang.
My shovel struck a hard object. It bounced backward and trembled in my hands. I fell to my knees and scooped away more mud.
A tingling sensation appeared in my fingertips as I felt the mysterious object. Hunahpu had been far more devious than I'd ever imagined.
"He outsmarted us." I shook my head. "He outsmarted us all."
"What are you babbling about?" Graham knelt on his good knee and felt around in the water. "What the hell is this stuff?"
"It's cement. Hydraulic cement. I'm willing to bet it rings the clearing, sort of like an ancient swimming pool." I exhaled. "In other words, this isn't a natural marsh. It's artificial."
Chapter 76
"I've got it," Renau shouted. "Over here."
I tossed my shovel to the side. Then I jogged down the long trench.
Rigoberta had spent the entire afternoon employing the tractor's backhoe just outside the eastern edge of the cement basin. She'd systematically removed tons of dirt and mud, forming a long, curving trench. Then I'd split the others into teams and sent them into the trench with shovels, in search of a water source. Apparently, our hard efforts had finally paid off.
Upon reaching Renau, I noticed a damaged rock formation. It was shaped like a pipe and lined with ancient cement. Water spurted out of it at an incredible clip, turning the ground at my feet into sludge. I gave it a long look and estimated the pipe's cross-section at just a few square inches. "Nice work. It's smaller than I expected. But that's got to be it."
"I think I know why it's so small," Beverly said. "It's to build water pressure. The pipe is probably a lot bigger on the other end. Gravity causes water to flow this way. The pipe gets skinnier, forcing the water into an increasingly small space. That's why it spurts out when it finally emerges."
"And that's how Hunahpu was able to spread the water through the marsh," I said slowly. "But how'd he keep it from overflowing?"
"He must've added some drains on the opposite side."
"God, he was clever." I exhaled. "Can you plug this up?"
"Sure. I just need to get my tools."
I climbed out of the trench and nearly ran into Emily. I quickly pulled her away from the others. "How are you?" I asked. "I didn't get a chance to talk to you after the attack."
"I'll miss Crowley. He was a loyal friend." She sighed. "I overheard your conversation. Do you really think you can stop the water?"
"I hope so."
"What do you want the rest of us to do in the meantime?"
"Just wait." I took a deep breath. "And hope like hell it works."
Chapter 77
Clutching the satphone in one hand, Miranda turned her head. The others were still gathered around the eastern edge of the marsh. She could barely see them through the mist.
She ran to the west. She got a good view of the outer tree line as she passed it. It was a series of gently swaying mammoth trunks that seemed to go on forever. They served in stark contrast to the tents. To the helicopter wreckage. To the piles of supplies and other items.
To her.
New civilization had secured a foothold in ancient nature. But she didn't care about that. She only cared about one thing.
Destroying the Library of the Mayas.
Miranda slid to a halt next to a tree grove. She still felt furious toward Pacho. Sure, she'd intended for him, along with everyone else, to die at the hands of Votan. But he couldn't have known about that. So, his efforts to undermine her work felt like the ultimate betrayal.
She stared into the sky, into the eyes of what the ancient Mayas had called Chaac. She loved archaeology. And Xibalba was undoubtedly the greatest find of her career. She could scarcely believe that it, along with the Maya Hero Twins, had actually existed. Unfortunately, no one else could ever know that.
Many years ago, she'd made a conscious decision to focus less on fact and more on the greater good. She'd sacrificed the quality of her research in order to make the world a better place. She'd felt guilty from time to time. But she'd never regretted the decision.
As a popular pundit, she'd used her knowledge of the past to predict the future. In that way, she'd been able to exert some control over political policies. And she intended to keep it that way, at least until the vast majority of people understood the dangers associated with manmade climate change.
