Roz hikes steadily up the mountain, forced by dense forest and rocky outcrops to zigzag and backtrack. After an hour, the robot reaches the craggy peak, where grasses, flowers, and shrubs grow in pockets of soil but no trees stand.

At the treeless summit, Roz is safe from falling pinecones. The robot climbs a leaning slab of stone to the highest point on the mountain and turns her head all the way around to survey the world below.

From the peak, Roz sees ocean stretching to the horizon in every direction. This reveals to Roz that she is on an island, clarifying the limits of her surroundings and the nature of her isolation.

Roz studies the island’s shape and landscape: a sandy southern point, widening green hills, sheer cliffs, a waterfall, a river, a meadow, wildflowers, ponds, boulders, and forest. As Roz refocuses her vision, the robot notices vultures, lizards, a badger, a moose, and sparrows, realizing the island is full of living creatures. The chapter ends by emphasizing that Roz, an artificial being, has become a new and strange kind of life on the island.
