ar from this station； her designer's best…laid plans went down the sewer。 The engines had the power； but Poulter had miscalculated the gear ratios。 The behemoth would do thirty miles an hour on a level road； but couldn't pull her mass through ice and snow； especially up a grade。 Given up as a white elephant； she was abandoned。 In later years； she was covered over by the ice； lost； and forgotten。 It was always thought that as the ice shelf moved toward the sea； the Snow Cruiser would eventually be carried away and dropped in the deep when the ice floe melted。〃
〃Where is she now； still buried under the ice？〃 Pitt inquired。
Cash shook his head and smiled。 〃The Snow Cruiser is about two miles from here； dangerously close to the edge of the ice shelf。 A rich old mining engineer got it into his head to find and rescue the vehicle； then transport it back to the States for display in a museum。 He and his crew discovered it thirty feet deep in the ice and spent three weeks digging it out。 They built an ice tent around it； and the last I heard actually got it running。〃
〃I wonder if they'd let us borrow it？〃
〃Never hurts to ask；〃 said Cash。 〃But I think you'd do better selling a basset hound on eating broccoli。〃
〃We've got to try；〃 Pitt said firmly。
〃You got Arctic clothing？〃
〃In the plane。〃
〃Better get it on。 We'll have to hike to where the Snow Cruiser sits。〃 Then Cash looked as though he'd suddenly thought of something。 〃Before I forget； I'll have a couple of our maintenance men throw a cover over your plane and set up an auxiliary heater to keep your engines； fuel； and hydraulic systems warm and the ice off the fuselage and wings。 Leave a plane set for a week and she'll start to disappear under a buildup of ice。〃
〃Good idea；〃 Giordino acknowledged。 〃We may have to use it in a hurry if all else fails。〃
〃I'll meet you back here in half an hour and I'll lead you to the vehicle。〃
〃Who is the old guy who's heading up the salvage operation？〃 asked Pitt。
Cash looked lost for a moment。 〃I don't really know。 He's an eccentric cuss。 His crew usually calls him 'Dad。' 〃
With Cash in the lead； they walked a trail marked with orange flags across the ice for nearly an hour。 After a while； Pitt could see figures moving about a large blue tent surrounded by a series of smaller orange polar tents。 A light snow was falling and forming a thin white blanket over the tents。 Strange as it seems； the Antarctic rarely experiences a heavy snow。 It is one of the driest continents on Earth； and a few inches below the surface； the snow is ancient。
There was almost no wind； but not having yet built an immunity against the icy temperatures； Pitt and Giordino felt cold beneath their heavy Arctic clothing。 The sun blazed through the remnants of the ozone layer； and the glare would have dazzled their eyes but for the darkly coated lenses of their glasses。
〃It looks nice and peaceful；〃 said Pitt； taking in the majestic view of the landscape。 〃No traffic； no smog； no noise。〃
〃Don't let it fool you；〃 Cash came back。 〃The weather can change into cyclonic hell in less time than you can spit。 I can't count all the fingers and toes that have been lost to frostbite。 Frozen bodies are found on a regular basis。 That's why anyone who works in the Antarctic is required to provide a full set of dental X rays and wear dog tags。 You never know when your remains will have to be identified。〃
〃Bad as that。〃
〃The windchill is the big killer。 People have taken a short hike only to be overtaken by high winds that block out all vision； and they freeze to death before finding their way back to the station。〃
They trudged the final quarter of a mile in silence； stepping over the crusted； wind…carved ice that thickened and pressed as it went deeper。 Pitt was beginning to feel the tentacles of exhaustion； too little sleep； and the pressures of the past few days； but the thought of falling into a bed never occurred to him。 The stakes were too high； fantastically so。 Yet his step was not as energetic as it should have been。 He noticed that Giordino was not walking lively； either。
They reached the camp and immediately entered the main tent。 The initial sight of the Snow Cruiser stunned them almost as much as when they'd viewed the Wolfs' gigantic ships for the first time。 The great wheels and tires dwarfed the men working around them。 The control cab that sat flush with the smooth front end rose sixteen feet into the air and brushed the top of the tent。 The top of the body behind the cab was flattened to hold the Beechcraft airplane that had not been sent to Antarctica with the big vehicle back in 1940。 It was painted a bright fire…engine red； with a horizontal orange stripe running around the sides。
The loud sound they had heard when approaching across the ice came from a pair of chain saws held by two men who were cutting grooves in the massive tires。 An old fellow with gray hair and a gray beard was supervising the crude method of cutting tread into rubber。 Cash stepped up to him and patted one shoulder to get his attention。 The old man turned； recognized Cash； and gestured for everyone to follow him。 He led the way outside and then into a smaller tent next door that contained the galley； with a small cookstove。 He offered them chairs around a long folding metal table。
〃There； that's quieter；〃 he said； with a warm smile； as he stared through blue…green eyes。
〃This is Dirk Pitt and Al Giordino with the National Underwater and Marine Agency；〃 said Cash。 〃They have an urgent mission for the government； and hope you can help them carry it out。〃
〃My name is a bit strange； so my crew； who are all forty years younger than I am； just call me Dad；〃 he said； shaking hands。 〃What can I do for you？〃
〃Haven't we met before？〃 asked Pitt； studying the old man。
〃It's possible。 I get around quite a bit。〃
〃The Snow Cruiser；〃 said Pitt； cutting to the heart of his request； 〃is it in any condition to drive to the South Pole？〃
〃That's what she was built to do； but if you'd have asked that question sixty years ago； or even a week ago； I'd have said no。 On dry land it proved a remarkable machine； but on the ice it was a dismal failure。 For one thing； the tires were smooth and spun ineffectively without friction。 And the gearing in the reduction unit was all wrong。 Driving her up a slight hill was like an eighteen…wheeler semi…truck and trailer attempting to pull a load up the Rocky Mountains in sixteenth gear。 The engine would lug itself to death。 By changing the gears and cutting treads in the tires； we think we can demonstrate that she might have lived up to expectations and actually reached the Pole。〃
〃What if she came up against a crevasse too wide for her to drive over？〃 inquired Giordino。
〃Thomas Poulter； the cruiser's designer and builder； came up with an ingenious innovation。 The big wheels and tires were positioned close to the center of the body； which left an overhang front and rear of eighteen feet。 The wheels were capable of retracting upward until they were level with the underside of the
