George Martin - Old Mars

The sled had more juice to be given, but I saved it because the more you used, the more sunlight you needed to keep it charged, and now, to make matters worse, the light was dropping down over the moving mountains. When nightfall came I would have power, but it sometimes faltered then, if the sled was given full throttle. Still, if I slowed too much, the shark would catch me. Crunch the craft in its great teeth, snapping it apart, getting to the gooey, tasty center inside, meaning, of course, me and my dad.

That shark couldn’t have known I would be more vulnerable come night, but it sure seemed to. It came fast behind me but was never able to catch me, even though I had only pushed the throttle a little more than before. Yet, it was like it knew I had limitations. That if all it did was wait, I would have to slow down and it would have me.

It was growing dark, but I could still see the line of mountains and the vast expanse of nothing around me, then all of a sudden the light washed out and the moons rose up. I turned on the lights.

And then it happened.

Even inside the sled, I could hear the ice crack, and then I could see them. I had never actually seen them for real, just vids, but there they were, cracking up through the ice and rising up and sliding along—the Climbing Bergs. They were rises of solid ice that came down from the depths where it was cold and wet and where the old, old Mars was. They would break open the surface and slide along and suck in the air. They were mounds of ice full of living organisms that owned them. Living organisms that came up for air and pulled it in and renewed themselves like Southern Earth ladies with handshaking fans on a hot day in church. Sometimes they were empty ice—clear ice you could see all the way through. And sometimes the ice held the ancient Mars inside of it. I had heard of that, extinct animals, and even Martians themselves, though there had only been fragments of that discovered, and most stories about them were legends, as the ice soon sank back down into the depths, taking their ancient treasures and information with them.

The ice cracked loud as doom and rose up and the moons flashed on the clean, clear ice, and the moonlight shone through it. It covered my entire path, and inside of the ice I could see something: a dark shadow. The shadow was in the center of the ice, and it was a shadow that covered acres and rose up high. Then I was close enough that I could see better what the shadow was. It almost took my breath away, almost made me forget about what was behind me. It was a slanting slide of ice that went directly up against the icy wall of the berg, and inside the berg was a huge set of stone stairs that rose up to a stone pyramid, and the stairs went inside and dipped into the dark. The ice between the outside and the pyramid looked thin, as if it might be hollow inside the berg.

I knew this much. I couldn’t keep outrunning the shark. In time the sunlight would wear, and the sled would slow. I had a sudden wild thought, but it was the only one I had. Besides, going around the berg might take hours; it was that big.

I glanced in the mirror and saw the shark’s fin, poking high, and I could see its shape shimmering beneath the ice. A huge shape, and I could see that it was, as I said, a monster that in spite of its name was really nothing like a shark. It was a dark form that was formless; it moved like gelatin, except for the fin, which stayed steady, sawing through the ice effortlessly.

Aiming the sled for the natural slide of ice, I gave the machine full throttle. I knew I was sacrificing some of my juice, but it was as good a plan as any I could think of.

I slid up the ice and came hard against the cold, clear wall of the berg, and killed the engine. I flipped the top and got out, leaned over and tore the supply bag open. Jerking out three of the thermal sticks, better known as flares, I gave them a twist and tossed them against the ice. They blossomed with flame. The flames rose up high and the heat singed my hair and made a kind of hissing sound as it melted a big hole in the ice. It was as I had hoped, a thin wall of ice, and inside, it was open; it was as if the ice were a glass cake cover of unusual shape and design, dipped over a pyramidal cake.

I looked back. The shark tore its whole body through the ice. It shifted and twisted and wadded, and finally it roared. It was a roar so loud I felt the ice beneath me shake. The roar and the wind carried its horrid breath to me. It was so foul I thought I might throw up. Its shape changed, became less flat and more solid, tentacles flashed out from its head, and I could see flippers on its belly, between those dipped little legs with bony hooks for feet. It was slithering and clawing its way across the cold space between me and it.

Back in the sled with the lid pulled down, I gunned forward and drove in and bounced up the steps, and then I was inside the pyramid. The lights on the sled showed me the way. I went along a large hallway, if something that large could be called a hall. On either side were strange statues of tall, thin creatures that resembled men. I zoomed by them and came to two wide-open doors made of something I couldn’t identify. They were wide enough for me to sled through, leaving several feet on either side.

Once I was inside, I grabbed a light from the supply bag, got out and tried to push one of the doors, but it was too heavy. Then I had an idea. I got back in the sled and circled it back against one of the doors and pushed, and it moved, slammed shut. I did the same with the other. I got out to make sure, flashed the light around. I could see there was a lock on the doors. It was too large for me to handle. I saw on one side of the door a rectangular gap. Running over there, I poked the light inside. There was a switch in there. I grabbed hold of it and tugged. It creaked and made a noise like a begging child, then I heard the lock slam into place. I had taken a guess, and I had been lucky. I had pulled the right switch, and the amazing thing still worked. It had most likely not moved since before the beginnings of civilization on Earth, and yet, there was no rust, no decay. It worked. A little squeaky, but otherwise, fully serviceable. If I hadn’t been in such a tight spot, I might have marveled even more at this turn of events.

It wasn’t really damp inside the pyramid. Inside its icy den it was clean and clear and there was air. If I remembered what I had read about the microscopic things in the ice, they would rise every now and then—maybe centuries passed before they rose—and they would suck at the air, and they would give off air as well, they would fill the void around them with it. Before, this had merely been speculation, but I was breathing that air and I could verify it. In fact, the atmosphere inside the pyramid was so rich it made me feel a little light-headed.

Then I heard the shark hit the door. It had come out of the ice and onto the steps. It struck the door hard. The door shook, but held. I crawled back inside the sled, and with the lights guiding my path, I drove it deeper into the structure’s interior.

I finally came to a large room, and, even more amazing, it was lighted. The lights were like huge blisters on the walls, and there were plenty of them. They gave off an orange glow. They were not strong lights, but they were more than adequate to see by. I killed the sled’s beams and engine, got out and looked around. At first, I couldn’t understand how the lights could exist, but then I thought about the old Martian technology that had been uncovered over the years. Things that had existed and survived and not decayed for millennia, such as that door lock. They had been so far ahead of us in many ways that it was impossible to comprehend. Add to that this strange iceberg, this thing made of ice and creatures that sealed off this world from water and decay, provided oxygen, then sunk back to the bottom of the sea, and it was enough to make my head spin.
