On a plinth to the left of the staircase there was a flat patch with a great view of the long narrow canyon below. He turned off the trail and stopped running. He sat down on a rock like a chair. It was windy; he popped his little mushroom tent, and it stood before him transparent in the dusk. Bedding, lamp, lectern, all pulled hastily from his fanny pack in the search for food, all burnished by years of use, and as light as feathers— his gear kit altogether weighed less than three kilos. And there they were in their place at the back, battery-powered stove and food bag and water bottle.

The twilight passed in Himalayan majesty as he cooked a pot of powdered soup, sitting cross-legged on his sleeping pad, leaning back against the tent’s clear wall. Tired muscles feeling the luxury of sitting down. Another beautiful day.

He slept poorly that night, and got up in the predawn cold wind, and packed up quickly, shivering, and ran west again. Out of the last Aromatum jumbles he came to the northern shore of Ganges Bay. The dark blue plate of the bay lay to his left as he ran. Here the long beaches were backed by wide sand dunes, covered by short grass that made for easy running. Nirgal flowed on, in his rhythm, glancing at the sea or into the taiga forest off to the right. Millions of trees had been planted along this coastline in order to stabilize the ground and cut down on dust storms. The great forest of Ophir was one of the least populated regions on Mars; it had been rarely visited in the earlier years of its existence, and had never been host to a tent town; deep deposits of dust and fines had discouraged travel. Now these deposits were somewhat fixed by the forest, but bordering the streams were swamps and quicksand lakes, and unstable loess bluffs that caused breaks in the lattice roof of branches and leaves. Nirgal kept to the border of forest and sea, on the dunes or among stands of smaller trees. He crossed several small bridges spanning river mouths. He spent a night on the beach, lulled to sleep by the sound of breaking waves.
