Among the new equipment is a big mushroom tent. They inflate it and climb in through the lock and up onto the tent floor for the night's party. Suddenly they are inside a giant transparent mushroom, bouncing over the soft clear raised floor like children on a feather bed; the luxury is excessive, ludicrous, inebriating. Champagne corks pop and fly into the transparent dome of the tent roof, and in the warm air they quickly get drunk, and tell each other how marvelous the climb was, how much they enjoyed it—the discomfort, exhaustion, cold, misery, danger, and fear already dissipating in their minds, already turning into something else.
The next day Marie is not at all enthusiastic about the remainder of their climb. “It's a walk up a bloody hill! And a long walk at that!"
“How else are you going to get down?” Eileen asks acerbically. “Jump?”
It's true; the arrangement they have made forces them to climb the cone of the volcano. There is a railway that descends from the north rim of the caldera to Tharsis and civilization; it uses for a rampway one of the great lava spills that erase the escarpment to the north. But first they have to get to the railway, and climbing the cone is probably the fastest, and certainly the most interesting, way to do that.
“You could climb down the cliff alone,” Eileen adds sarcastically. “First solo descent . . .”
Marie, apparently feeling the effects of last night's champagne, merely snarls and stalks off to snap herself into one of the cart harnesses. Their new collection of equipment fits into a wheeled cart, which they must pull up the slope. For convenience they are already wearing the space suits that they will depend on higher up; during this ascent they will climb right out of most of Mars's new atmosphere. They look funny in their silvery green suits and clear helmets, Roger thinks; it reminds him of his days as a canyon guide, when such suits were necessary all over Mars. The common band of the helmet radios makes this a more social event than the cliff climb, as does the fact that all seven of them are together, four hauling the cart, three walking freely ahead or behind. From climb to hike: The first day is a bit anticlimactic.
On the snowy southern flank of the volcano, signs of life appear everywhere. Goraks circle them by day, on the lookout for a bit of refuse; at dusk ball owls dip around the tent like bats. On the ground Roger sees marmots on the boulders and volcanic knobs, and in the system of ravines cut into the plateau they find twisted stands of Hokkaido pine, chir pine, and noctis juniper. Arthur chases a pair of Dall sheep with their curved horns, and they see prints in the snow that look like bear tracks. “Yeti,” Dougal says. One mirror dusk they catch sight of a pack of snow wolves, strung out over the slope to the west. Stephan spends his spare time at the edges of the new ravines, sketching and peering through binoculars. “Come on, Roger,” he says. “Let me show you those otterines I saw yesterday."
“Bunch of mutants,” Roger grumbles, mostly to give Stephan a hard time. But Eileen is watching him to see his response, and dubiously he nods. What can he say? He goes with Stephan to the ravine to look for wildlife. Eileen laughs at him, eyes only, affectionately.
Onward, up the great hill. It's a six-percent grade, very regular, and smooth except for the ravines and the occasional small crater or lava knob. Below them, where the plateau breaks to become the cliff, the shield is marked by some sizable mesas—features, Hans says, of the stress that broke off the shield. Above them, the conical shape of the huge volcano is clearly visible; the endless hill they climb slopes away to each side equally, and far away and above they see the broad flat peak. They've got a long way to go. Wending between the ravines is easy, and the esthetic of the climb, its only point of technical interest, becomes how far they can hike every day. It's 250 kilometers from the escarpment up to the crater rim; they try for twenty-five a day, and sometimes make thirty. It feels odd to be so warm; after the intense cold of the cliff climb, the space suits and the mushroom tent create a distinct disconnection from the surroundings.
Hiking as a group is also odd. The common band is a continuous conversation, that one can switch on or off at will. Even when not in a mood to talk, Roger finds it entertaining to listen. Hans talks about the areology of the volcano, and he and Stephan discuss the genetic engineering that makes the wildlife around them possible. Arthur points out features that the others might take for granted. Marie complains of boredom. Eileen and Roger laugh and add a comment once in a while. Even Dougal clicks into the band around midafternoon, and displays a quick wit, spurring Arthur toward one amazing discovery after another. “Look at that, Arthur, it's a yeti.”
