The Cordillera is the longest fold mountain system in the world, a jagged spine running the length of the North and South American continents. It stretches nearly 15,000 kilometers from the frozen reaches of Alaska to the tip of Tierra del Fuego.
The northern section, where James's family now traveled, is the Rocky Mountains; the southern half is known as the Andes.
Currently, they were traversing the southern Rockies atop the Colorado Plateau—the same region that held the massive scars of the Grand Canyon they had crossed months prior. James looked out over the landscape. It was a high-altitude desert plateau, a desolate vista of stacked sand mountains and rolling dunes that bled into a barren wilderness of rock and scrub.
As the sun dipped low, the family found a patch of level ground and settled in for a much-needed rest. A full day of migration had left their muscles heavy.
James, however, remained awake. He watched the stars beginning to prick through the darkening sky. He wasn't counting them for amusement; he was confirming the path for the next day's march. His anchor was the North Star.
Northern sky... there.
James climbed to a high outcrop and tilted his head back. Without the light pollution or smog of a future civilization, the air here was pristine. The stars were sharp, brilliant pinpoints against the black.
Because the North Star (Polaris) sits almost directly above the Earth's rotational axis, its position remains fixed while the rest of the heavens revolve around it. It is the permanent compass of the Northern Hemisphere.
"Dad and Mom have the right heading... it's strange. How do they know?"
James watched his parents. Throughout this massive trek from the Mississippi plains to the Rockies, they had never faltered. He wondered if they possessed some form of internal navigation—perhaps an instinctual map of the Earth's magnetic fields.
He knew from his human knowledge that many migratory birds used magnetoreception to navigate, effectively carrying a built-in GPS in their brains. Whether a Smilodon possessed such a gift remained a mystery to him; he hadn't felt any internal compass. He had to rely on human logic and celestial landmarks like the sun, the moon, and the stars.
WHOOOO—
Suddenly, a violent, biting wind roared in from the west. It kicked up a wall of choking dust instantly. The light of the North Star was smothered, turning into a dim, pale ghost behind a veil of grit.
The sudden shift caused a stir among the sleeping animals in the valley. A low hum of unrest rippled through the hills.
"What is this?"
James watched the horizon, his ears pinned back. This ecosystem was vastly different from the lush plains or the dense mountain forests. He lacked the experience for this terrain.
But his predatory instincts were screaming. Something was changing.
Aside from the wind, the night passed without further incident. But when morning arrived and James looked at the sky, his heart sank.
WHOOOO—
The wind wasn't a gale yet, but it was restless, surging in rhythmic pulses. The sky had turned a sickly, bruised yellow. Floating silt and sand saturated the air, creating a dim, oppressive haze. The scent of ozone and parched earth was suffocating.
"ROAR~~"
James wasn't the only one on edge. Mom and Dad were pacing, their breaths coming in short, labored hitches as the dust began to clog their nostrils. Zack and Zoe huddled close, whimpering at the sudden drop in air quality.
"We can't move in this. Is it a sandstorm?"
James looked toward the western horizon and felt a cold jolt of terror.
Sandstorms—or Haboobs—were among North America's most lethal natural disasters. The Colorado Plateau was a prime breeding ground for them. It was a land of vast, arid basins with extreme temperature swings. During the transition from winter to spring, these storms were a frequent, violent occurrence.
For humans, these storms meant collapsed structures and choked power grids. For wild animals, they were a trial of life and death. A single major event could wipe out entire herds.
All around them, the local wildlife was in a panic. Small mammals scurried for deep burrows; birds took to the sky in a desperate attempt to outrun the front.
"We need cover. Now."
James's muscles tensed. The freak wind from the night before had been the warning shot. Now, visibility was collapsing. The wind began to truly howl, its speed climbing with terrifying momentum. James felt as though his field of vision was being cut away by a yellow blade of sand.
They were in the open. There was nothing to break the wind here.
"HOOOO!!"
The family pushed forward, heads low against the stinging grit.
RUMBLE—
A deep, bone-shaking roar erupted from the distance. It wasn't thunder; it was a continuous, vibrating drone that seemed to shake the very earth beneath their paws.
James looked back to the west.
A shimmering, jagged yellow line had appeared on the horizon. Within seconds, that line transformed into a rolling, churning wall of sand and debris. It was a gargantuan beast of earth, rising over a hundred meters into the air, screaming toward them.
The sandstorm had arrived.
WHOOSH—
The world vanished. The sun was swallowed whole, plunged into a premature night as the wall of sand slammed into the plateau. It looked like the end of the world.
