achine had proven herself a tough customer。 Engines running faultlessly； wheels churning through the snow and ice； she never stalled or floundered during the malicious blizzard。 But for the muffled tone of her exhaust； the stillness that settled over the desolate ice shelf made it seem like oblivion。
Warmed finally by the engines； Pitt felt ready to face reality again。 He took over the wheel from Giordino； who found a broom in the bunk partment and used it to brush the ice buildup off the windshields。 Released from their frozen bondage； the windshield wipers finished sweeping the glass clean。 The Rockefeller Mountains materialized in the distance and rose above the bow of the vehicle。 They were that close。
Pitt pointed to a series of black smudges on the sun…splashed white horizon slightly off to his left。 〃There lies the Wolf mining works。〃
〃We did good；〃 said Giordino。 〃We couldn't have wandered more than a mile off our original track during the storm。〃
〃Another three or four miles to go。 We should be there in twenty minutes。〃
〃Are you going to crash the party unannounced？〃
〃Not a wise move against an army of security guards；〃 answered Pitt。 〃That low rock ridge protruding from the ice that angles toward the base of the mountains？〃
〃I see it。〃
〃We can run along out of sight of the pound； using it for cover while we close the final two miles。〃
〃We just might make it；〃 said Giordino； 〃if they don't spot our exhaust。〃
〃Keep your fingers crossed；〃 Pitt said with a tight grin。
They left the great ice plain of the Ross Ice Shelf and crossed onto ice…mantled land and skirted the ridge that trailed down from the mountain like a giant tongue； keeping below the summit out of sight of the mining pound as they crept ever closer。 Soon they were driving beneath towering gray rock cliffs； with streams of ice hanging from their crests like frozen waterfalls； gleaming blue…green under the radiant sun。 The path they took along the base of the mountains was not flat or smooth but strewn with wavelike undulations。
Pitt downshifted the Snow Cruiser into second gear to climb the series of low mounds and valleys。 The burly machine took the uneven terrain in stride； her wide wheels moving the great mass up and down the grades without effort。 His eyes swept the instrument panel for the tenth time in as many minutes。 The temperature gauges indicated that the slow speeds at high rpms were causing the diesels to overheat again； but this time they could keep the door open without suffering the agonies of a blizzard。
They were passing the mouth of a narrow box canyon when Pitt suddenly stopped the Snow Cruiser。
〃What's up？〃 Giordino asked； staring at Pitt。 〃You see something？〃
Pitt pointed downward through the windshield。 〃Tracks in the snow leading into the canyon。 They could have only been made by the treads from a big Sno…cat。〃
Giordino's eyes followed Pitt's outstretched finger。 〃You've got good eyes。 The tracks are barely visible。〃
〃The blizzard should have covered them；〃 said Pitt。 〃But they still show because the vehicle that made them must have passed through just as the storm was ending。〃
〃Why would a Sno…cat travel up a dead…end ravine？〃
〃Another entrance to the mining pound？〃
〃Could very well be。〃
〃Shall we find out？〃
Giordino grinned。 〃I'm dying of curiosity。〃
Pitt cranked the steering wheel to its stop and sharply turned the Snow Cruiser into the canyon。 The cliffs rose ominously above the ravine； their height escalating until the sun's light paled the deeper they drove into the mountain。 Fortunately； the twists and turns were not severe； and the Snow Cruiser was able to deftly navigate her bulk around and through them。 Pitt's only worry was that they'd find nothing but a rock wall； and then have to back the vehicle through the canyon； since there was no room to turn her around。 A quarter of a mile from the canyon's mouth； Pitt braked the vehicle to a stop before a solid wall of ice。
It was a dead end。 Disillusionment circled their minds。
They both stepped down from the Snow Cruiser and stared at the vertical sheet of ice。 Pitt peered down at the tracks that traveled up the canyon and stopped at the wall。 〃The plot thickens。 The Sno…cat could not have backed out of here。〃
〃Certainly not without making a second set of tracks；〃 observed Giordino。
Pitt moved until his face was inches from the ice； cupped his hands around his eyes to block out the light； and stared。 He could make out vague shadows beyond the ice barrier。 〃Something is in there；〃 he said。
Giordino gazed into the ice and nodded。 〃Is this where somebody says； ‘Open Sesame'？〃
〃No doubt the wrong code；〃 Pitt said pensively。
〃It has to be a good three feet thick。〃
〃Are you thinking what I'm thinking？〃
Giordino nodded。 〃I'll stay on the ground outside and cover you with my Bushmaster。〃
Pitt climbed back into the Snow Cruiser； shifted the gear lever into reverse； and sent the vehicle back about fifty feet； keeping the tires in the packed depressions made by the Sno…cat for better traction。 He paused； grasped the wheel tightly in both hands； and burrowed down in the seat； in case the ice should crash through the windshield。 Then he shifted into first and jammed the accelerator pedal flat against the floorboards。 With a roar from its exhaust； the big mechanical goliath leaped forward； gathered speed； and then smashed into the frozen wall； rumbling the ground beneath Giordino's feet。
The ice exploded and shattered into a great splash of glittering fragments that showered over the red Snow Cruiser like so many glass shards from a fallen crystal chandelier。 The sound of the impact came like a giant gnashing his teeth。 At first； Giordino thought the vehicle might have to ram the thick； solidified ice wall several times before breaking through； but he was almost left behind as it bulldozed its way through on the first try and disappeared on the other side。 He chased after it； gun cradled in his arms； like an infantryman following a tank for cover。
Once through； Pitt brought the Snow Cruiser to a halt and brushed the glass from his face and chest。 A large block of ice had burst through the center windshield； narrowly missing him before it fell to the floor and shattered。 His face was cut on one cheek and across the forehead。 Neither gash was deep enough to require stitches； but the blood that flowed made him look as though he were badly injured。 He wiped the crimson from his eyes onto his sleeve and looked to see where the Snow Cruiser had e to rest。
They were sitting inside a large…diameter ice tunnel； with the vehicle's front end firmly embedded in a frozen wall opposite the shattered entry。 In both directions the tunnel looked deserted。 Seeing no sign of hostility； Giordino rushed into the Snow Cruiser and climbed the ladder to the control cabin。 He found Pitt smiling hideously through a mask of blood。
〃You look bad；〃 he said； attempting to help Pitt from the driver's seat。
Pitt gently pushed him away。 〃It's not nearly as bad as it lo
