The Davis-based New York Times best-selling author is celebrated for epic sci-fi novels, including his classic Mars trilogy about terraforming the Red Planet and The Ministry for the Future about solving the climate crisis, which former President Barack Obama named as one of his favorite books of 2020. But in his new memoir The High Sierra: A Love Story, which comes out on May 10, Kim Stanley Robinson takes a turn for the terrestrial, covering a half-century of writing, thinking and adventuring across our altitudinous backyard, tracing the origins of both backpacking and environmentalism. He talks to us about entering the God zone while hiking, being a “utopian science fiction writer,” and why despite a certain tech billionaire’s predictions, we won’t be living on Mars anytime soon.
