Fast forward to a couple of months ago, when I stumbled upon Ronald Hamilton’s paper “The Silent Fire: ODAP and the Death of Christopher McCandless,” which Hamilton had posted on a Web site that publishes essays and papers about McCandless. Hamilton’s essay offered persuasive new evidence that the wild-potato plant is highly toxic in and of itself, contrary to the assurances of Thomas Clausen and every other expert who has ever weighed in on the subject. The toxic agent in Hedysarum alpinum turns out not to be an alkaloid but, rather, an amino acid, and according to Hamilton it was the chief cause of McCandless’s death. His theory validates my conviction that McCandless wasn’t as clueless and incompetent as his detractors have made him out to be.

Hamilton’s discovery that McCandless perished because he ate toxic seeds is unlikely to persuade many Alaskans to regard McCandless in a more sympathetic light, but it may prevent other backcountry foragers from accidentally poisoning themselves. Had McCandless’s guidebook to edible plants warned that Hedysarum alpinum seeds contain a neurotoxin that can cause paralysis, he probably would have walked out of the wild in late August with no more difficulty than when he walked into the wild in April, and would still be alive today. If that were the case, Chris McCandless would now be forty-five years old.

20 years after he wrote Into the Wild, the now-legendary tragedy-turned-movie of how 24-year-old Chris McCandless perished in the wilderness, Jon Krakauer revisits the facts of how McCandless actually died, thanks to a compelling example of citizen science and citizen journalism.
