lava-dike-geology

Ann Clayborne investigates the Geneva Spur, a basalt lava dike exposed by erosion in Melas Chasma on Mars, collecting geological samples and observing signs of accelerated erosion due to terraforming. During her study, a massive long runout landslide occurs at Cape Solis, threatening her safety; she experiences the landslide's force but survives, reflecting on past losses and the irreversible consequences of terraforming. The chapter explores geological mysteries of Mars alongside Ann's personal confrontation with mortality and the planet's changing environment.
