This is the final part of the Anton deGama story, Black Ice. If you haven't read the preceding parts, this probably won't make a lot of sense (but the rest of the story is still on the blog, so you could always start at the beginning!). Anton has, against all the odds, driven the crawler over the trench, escaping the sliding ammonia ice.
Anton slowed the engine, letting the tracks get a grip on the mercifully solid ground beyond the trench. He looked back as the ammonia frostslide continued to tumble into the depths, and briefly thanked his lucky stars.
He sealed his suit and picked up a can of screen gel, before coating the stars in the crawler's canopy. He could not replace the harpoon until he got back to Groundstation. He glanced at the chart. The trench bisected the range of hills neatly, and he was on the wrong side from the weather station.
He sighed, and started the engine. He had a long way to go. After all, he needed the money. And he doubted Groundstation would accept that a minor problem en route justified abandoning the trip.
As always, comments appreciated!
