Ann travels across Mars, investigating geological features such as the Chryse Trough and the ice sea formed by glaciers, while reflecting on the planet's ancient terrain and the history of its naming conventions. She grapples with fading memories and the randomness of survival amid past violent events, focusing on her scientific work despite the haunting presence of past disasters. The chapter explores Mars's geological history, the impact of human conflict, and the psychological effects of isolation and memory loss.

In this chapter, Sax travels from Pavonis to a Red outpost in Tempe Terra to find Ann, who has withdrawn from the longevity treatment and appears physically deteriorated. Their strained interaction reveals Ann's disillusionment and emotional withdrawal, while Sax attempts to reconnect through shared scientific inquiry and exploration of Mars' evolving landscape. The chapter explores themes of isolation, the passage of time, and the tension between scientific progress and personal decline.

In this chapter, Ann Clayborne explores the ancient and rapidly changing landscape of Tempe Terra on Mars, observing the melting permafrost and geological transformations. She encounters a group of young Red ecoteurs who advocate for militant resistance against terraforming efforts, but Ann urges a shift towards nonviolent stewardship and cultural reverence for Mars' primal red landscape. Together they visit the icy northern sea and reflect on the future of Mars, emphasizing the need for a new form of areophany that honors the planet's original character rather than green terraforming.

Sax Russell searches for Ann Clayborne on Olympus Mons after discovering her wristpad was left behind, indicating she is climbing in the caldera. He travels down into the vast, multiringed caldera, reflecting on its geological features and the stark, primordial Martian environment. Upon finding Ann at a remote hut, their emotionally charged reunion reveals unresolved tensions and concern over recent events involving mutual acquaintances.

This chapter provides a detailed geological and atmospheric history of Mars, explaining its formation, major surface features like the Tharsis Bulge and impact basins, and the cycles of water and ice shaping its environment. It then transitions to a first-person narrative of Nadezhda Francine Cherneshevsky's initial experience walking on Mars, highlighting the physical sensations of reduced gravity, the harsh cold, and the presence of pre-deployed equipment for colonization. The chapter juxtaposes Mars' ancient, austere natural history with the human arrival and the beginning of active exploration and settlement.
