I finished The Humboldt Current at noon on a glorious spring day in northern California. Sachs concludes with a call to follow the work of Alexander von Humboldt: get lost in nature, allow it to overtake you even in everyday life. So I set off from my in-laws' home in the hills of the East Bay, and made my way to the local park nestled at the top of a ridge. Just as I have for the last ten years, I passed a sign that read “No Trespassing”—a message reinforced with barbed wire. Emboldened by Sachs and the spirit of Humboldt, I defied the sign, slipped the fence, and followed a footpath to the most spectacular views of the Bay I have ever experienced. Each bend rewarded me with verdant hillsides, wildflowers, and canyons. How could I have gone so many years without taking this path?

Robinson is currently working on a cultural history of exploration in the nineteenth century, and—like Sachs—considers Humboldt a foundational figure in this story.

5 I suspect that part of Humboldt's appeal had to do with his ability to graphically represent complex information. The cross-sectional and isothermal maps mentioned above are just two examples of the images he created that schoolbook authors reproduced widely for their visual appeal. Humboldt himself was intrigued by the graphic visualization of knowledge, which could “speak to the senses without fatiguing the mind.” Headrick, Daniel, When Information Came of Age: Technologies of Knowledge in the Age of Reason and Revolution, 1700–1850 (New York: Oxford University Press, 2000), 129Google Scholar.
