Amazonia

"Besides;" Nate said, "we have a man down. The sooner we reach a village or whatever, the better Frank's chances. I say we forge on:"

Kostos sighed, then nodded. "Okay, but keep together:"

The sergeant straightened and led the way from there.

With each step, the new day grew brighter. Sunrise in the Amazon was often sudden. Overhead, the stars were swallowed in the spreading rosy glow of dawn. The cloudless sky promised a hot day to come.

The group paused at the top of the chasm. A thin trail led down into the jungle. But where did it go? In the valley below, there was no sign of habitation. No wood smoke rising, no voices echoing.

Before moving forward, Kostos stood with binoculars, studying the valley. "Damn it," he mumbled.

"What's wrong?" Zane asked.

"This canyon is just a switchback of the one we were in:" He pointed to the right. "But it appears this canyon is cut off from the one below it by steep cliffs:"

Nate lifted his own binoculars and followed where the sergeant pointed. Through the jungle, he could just make out where a small stream flowed down the canyon's center. He followed its course until it vanished over a steep drop, down into the lower canyon, the one they had been marching through all night, the domain of the giant jaguars.

"We're boxed in here," Kostos said.

Nate swung his binoculars in the opposite direction. He spotted another waterfall. This one tumbled down into this canyon from a massive cliff on the far side. In fact, the entire valley was closed in by rock walls on three sides, and the steep cliff on the fourth.

It's a totally isolated chunk of jungle, Nate realized.

The sergeant continued, "I don't like this. The only way up here is this chute:"

As Nate lowered his glasses, the edge of the sun crested the eastern skies, bathing the jungle ahead in sunlight, creating a green glow. A flock of blue-and-gold macaws took wing from a rookery near the misty cliffs and sailed past overhead. The spray from the two waterfalls at either end of the valley made the air almost sparkle in the first rays of the sun.

"Like a bit of Eden," Professor Kouwe said in a hushed voice.

With the touch of light, the jungle awoke with birdsong and the twitter of monkeys. Butterflies as big as di

But what else had made its home here?

"What are we going to do?" A

Everyone remained silent for several seconds.

Nate finally spoke. "I don't think we have much choice but to proceed:"

Kostos scowled, then nodded. "Let's see where this leads. But stay alert:"

The group cautiously descended the short slope to the jungle's edge. Kostos led once again, Nate at his side with his shotgun. They marched in a tight bunch down the path. As soon as they entered under the bower of the shadowed forest, the scents of orchids and flowering vines filled the air, so thick they could almost taste it.

Still, as sweet as the air was, the constant tension continued. What secrets lay out here? What dangers? Every shadow was suspect.

It took Nate fifteen minutes of hiking before he noticed something strange about the forest around them. Exhaustion must have dulled his senses. His feet slowed. His mouth dropped open.

Ma

His brow furrowed, Nate crossed a few steps off the path.

"What are you doing, Rand?" Kostos asked.

"These trees. . :" Nate's sense of wonder overwhelmed him, cutting through his unease.

The others stopped and stared. "What about them?" Ma

Nate turned in a slow circle. "As a botanist, I recognize most of the plants around here:" He pointed and named names. "Silk cotton, laurels, figs, mahogany, rosewood, palms of every variety. The usual trees you'd see in a rain forest. But. . :" Nate's voice died away.

"But what?" Kostos asked.

Nate stepped to a thin-boled tree. It stretched a hundred feet into the air and burst into a dense mass of fronds. Giant serrated cones hung from its underside. "Do you know what this is?"

"It looks like a palm," the sergeant said. "So what?"

"It's not!" Nate slapped the trunk with his palm. "It's a goddamn cycadeoid:"

"A what?"

"A species of tree thought long extinct, dating back to the Cretaceous period. I've only seen examples of it in the fossil record:"

"Are you sure?" A

Nate nodded. "I did my thesis on paleobotany." He crossed to another plant, a fernlike bush that towered twice his height. Each frond was as tall as he was and as wide as his stretched arms. He shook one of the titanic leaves. "And this is a goddamn giant club moss. It's supposed to have gone extinct during the Carboniferous period. And that's not all. They're all around us. Glossopterids, lycopods, podocarp conifers . . :" He pointed out the strange plants. "And that's just the things I can classify."

Nate pointed his shotgun to a tree with a coiled and spiraled trunk. "I have no idea what that thing is:" He faced the others, shedding his exhaustion like a second skin, and lifted his arms. "We're in a goddamn living fossil museum:"

"How's that possible?" Zane asked.

Kouwe answered, "This place is isolated, a pocket in time. Anything could have sheltered here for eons:"

"And geologically this region dates back to the Paleozoic era," Nate added, excited. "The Amazon basin was once a freshwater inland sea before changes in tectonics opened the sea to the greater ocean and drained it away. What we have here is a little peek at that ancient past. It's amazing!"

Kelly spoke up from beside the stretcher. `Amazing or not, I need to get Frank somewhere safe:'

Her words drew Nate back to the present, back to their situation. He nodded, embarrassed at his distraction in the face of their predicament.

Kostos cleared his throat. "Let's push on:"

The group followed his lead.

Fascinated by the forest, Nate hung back. His eyes studied the foliage around him, no longer peering at the shadows, but fixed on the jungle itself. As a trained botanist, he gaped in disbelief at the riotous flora: stalked horsetails the size of organ pipes, ferns that dwarfed modern-day palms, massive primitive conifers with cones the size of VW bugs. The mix of the ancient and the new was simply astounding, a merged ecosystem unlike any seen before.

Professor Kouwe walked beside him now. "What do you think about all this?"

Nate shook his head. "I don't know. Other prehistoric groves have been discovered in the past. In China, a forest of dawn redwoods was discovered in the eighties. In Africa, a grotto of rare ferns. And most recently, in Australia, an entire stand of prehistoric trees, long thought extinct, was found in a remote rain forest:" Nate glanced to Kouwe for emphasis. "So considering how little of the Amazon has been explored, it's actually more surprising that we've not found such a grove before:"

"The jungle hides its secrets well," Kouwe said.

As they walked, the canopy overhead grew denser, the forest taller. The morning sunlight dwindled to a green glow. It was as if they were walking back into twilight.

Further conversation died as everyone watched the forest. By now, even nonbotanists could tell this jungle was unusual. The number of prehistoric plants began to outnumber the modern-day counterparts. Trees grew huge, ferns towered, strange twisted forms wound among the mix. They passed a spiky bromeliad as large as a small cottage. Massive flowers, as large as pumpkins, grew from vines and scented the air thickly.
