cape of beauty and magnificence. It could be tranquil one moment and frightening the next. In Pitt's mind, it suddenly became frightening. His feet stomped the brake and clutch of the Snow Cruiser, and he watched stunned as a crevasse no more than a hundred feet away opened and spread apart, the crack stretching as far as he could see in both directions across the ice pack.
Dropping down the ladder from the control cabin, he threw open the entry door, stepped outside, and walked to the edge of the crevasse. It was a terrifying sight. The color of the ice on the sides that fell out of sight turned from white at the edge of a beautiful silver-green. Its gap spanned almost twenty feet. He turned as he heard the crunch of Giordino's feet behind him.
"What now?" questioned Giordino. "This thing must run forever."
"Frank Cash mentioned that the wheels could retract to cross crevasse. Let's check out the operation manual that Dad gave us."
As Dad had told them, the Snow Cruiser's designer, Thomas Poulter, had come up with an ingenious solution for the crevasse problem. The underside of the cruiser's belly was flat like a ski, with a front and rear overhang of eighteen feet on both ends from the wheels. Following the instructions in the manual, Pitt pressed the levers that retracted the front wheels vertically until they were level with the body. Then, using the rear wheels for traction, he drove the Cruiser slowly forward until the front section slid across the crevasse and rolled past the opposite edge a safe distance for stability. Next Pitt extended the front wheels and retracted the wheels in the rear. Now using the front-wheel drive, the rear half of the cruiser was pulled the rest of the way over the chasm. After, extending the rear wheels, they were on their way again.
"I do believe I'd call that a brilliant innovation," Giordino said admiringly.
Pitt shifted gears and turned the bow of the Snow Cruiser back toward the peak that had expanded into a range of mountains. "Amazing how he could be farsighted on one mechanism and yet badly underestimate the gearing and tire tread."
"No one is flawless. Except me, of course.'
Pitt accepted the bluster with practiced patience. "Of course."
Giordino took the manual with him into the engine compartment, but not before pointing to the twin temperature gauges on the instrument panel. "The engines are running hotter than normal. Better keep an eye on them."
"How can they run hot when it's twenty degrees below zero outside?" Pitt queried.
"Because their radiators are not exposed. They're mounted directly in front of the engines inside the compartment. It's almost as if they overheat themselves."
Pitt had hoped darkness would cloak their arrival at the mining compound, but at this time of year in the Antarctic, the sunset had barely occurred before it was dawn again. He didn't fool himself into thinking they could infiltrate the facility without being detected, certainly not in a gargantuan fire-engine-red snow vehicle. He knew he'd have to think of something in the next hour and a half. Soon, very soon, the buildings of the extraction plant would appear on the horizon along the base of the mountains.
He began to feel a tinge of hope, but then, as if an unseen force was working against him, the atmosphere grew heavy and congealed like a lace curtain. The wind suddenly swept in from the interior of the continent with the force of a tidal wave. One minute, Pitt could see for sixty miles. The next it was as though he was gazing through a film of water, fluid in motion, iridescent and ephemeral. The sky was gone in the blink of an eye and the sun totally blotted out, as the wind charged over the ice shelf like a raging monster. The world became a swirling pall of pure white.
He kept the accelerator pressed to the metal floor and clenched the steering wheel, not turning it, keeping the big vehicle moving in a straight line. They were in a hurry, and no tempestuous behavior from Mother Nature was going to slow them down.
A man wanders in circles during a whiteout, not because he's right-handed and tends to go in that direction, but because almost all humans unknowingly have one leg that is a millimeter shorter than the other. The same factor held true with the Snow Cruiser. None of the tires had come out of the mold symmetrically perfect with each other. If the steering wheel was locked in place while the vehicle was moving straight, it would gradually begin turning in an arc.
Nothing held substance. It was as if the world no longer existed. The gale-force windstorm seemed to drain the color out of everything. The ice storm swirled and gusted with such force that the driving hail of ice particles bombarded the windshield like tiny nails. Their impact against the glass came like a crescendo of clicking sounds. Pitt felt himself idly wondering if the onslaught would mar the old prewar safety glass. He lurched forward as the Snow Cruiser bounced over a frozen ice ridge unseen under the white maelstrom. He braced for a second bump, but it never came. The ice ran smooth.
The old line "It never rains but it pours," flashed through Pitt's mind when Giordino shouted through the hatch from the engine compartment, "Check your gauges. The engines are still running hot. With no air circulation down here, I have steam coming out of the radiator overflow tubes."
Pitt stared at the temperature gauges on the instrument panel. He'd spent so much effort concentrating on keeping the great vehicle moving on an undeviating course, he'd neglected to check the gauges. Oil pressure was slightly low, but the water temperatures were already crossing into the red zone. In less time than it takes to boil an egg, the radiators would boil over and blow a water hose from the engine.
After that, there was no way of telling how long the engines would turn until their pistons burned and froze inside the cylinders. Already, he could hear the engines beginning to misfire as combustion occurred early from the acute heat.
"Throw on your cold-weather gear," Pitt shouted. "When you're ready, open the outside door. The flood of cold air should cool down the engines."
"And freeze us into Popsicles at the same time," Giordino came back.
"We'll have to suffer until they're running at normal temperatures again.
Both men donned their heavy-weather coveralls and hooded parkas again, Pitt struggling with the heavy clothing while he kept the Cruiser on a steady course through the storm. When they were fully dressed and fortified for the cold, Giordino opened the door. A howling chaos surged into the control cabin, the wind moaning and screaming as it whipped through the doorway. Pitt huddled over the steering wheel and stared through half-screwed-shut eyes as the blast of cold flung itself into the control cabin with a banshee shriek that drowned out all sounds from the diesel engines.
He could not have envisioned the profound shock that came from having the temperature inside the cabin drop eighty degrees within thirty seconds. When a human is appropriately clothed for extreme cold, he can endure temperatures of 120 degrees below freezing for twenty to thirty minutes at a time without suffering injury. But when the windchill factor adds another fifty degrees to the temperature, the drastic frigidness can kill within a few short minutes. Pitt's cold-weather clothing could protect him from mere cold, but the chill from the gale sucked the body heat right out of him.
Down in the engine compartment, Giordino sat between the two engines and savored what little heat he could soak up from the exhaust heaters and the radiator fans. He was deeply concerned about how Pitt could survive until the engine temperatures dropped. There was no more communication. The screaming wind made voice contact impossible.
The next few minutes were the longest Pitt had ever spent. He had never known such cold. It felt as if the wind went right through him, cutting his insides as it traveled. He stared at the needles on the engine temperature gauges and saw them drop with agonizing slowness. The ice crystals smashed into the windshields like a never-ending swarm. They hurtled through the door and into the control cabin, quickly covering Pitt and the instrument panel in a white glaze. The heater could no longer cope with the frozen air, and the inside of the windshield quickly frosted over, while the wipers on the outside were overwhelmed and soon became locked in a thickening blanket of ice. Unable to see past the steering wheel, Pitt sat like a rock as the torrent of white curled around him. He felt as though he were being swallowed by a ghost with thousands of tiny teeth.
He clenched his own teeth to keep them from chattering. Fighting forces far beyond his control, and realizing that he might be responsible for saving billions of lives, was not pleasant, but it drove him to stay the course against the screaming wind and stinging ice. What frightened him most was the prospect of driving into a crevasse that was impossible to see before it was too late. The sane thing to do was to slow the Snow Cruiser to a snail's crawl and send Giordino ahead to test the ice, but besides risking his friend's life, it would have cost them precious time, and time was an extravagance they did not have. His numbed right foot could no longer move up and down on the accelerator pedal, so he kept it fully pressed down, frozen in place to the floorboard.
Their drive across that deceptive and treacherous ice field had turned into a freezing nightmare.
There was no point of no return. It was finish the mission or die. The shrieking fury of the ice storm showed no signs of diminishing. Pitt wiped the thickening veneer of ice from the instrument panel at last.
