Christopher Johnson McCandless (February 12, 1968 – August 1992) was an American Adventurer who adopted the alias Alexander Supertramp and hiked into the Alaskan wilderness in April 1992 with little food and equipment, hoping to live simply for a time in solitude. Almost four months later, McCandless’ remains were found, weighing only 67 pounds (30 kg); he died of starvation near Lake Wentitika in Denali National Park and Preserve.

Inspired by the details of McCandless’s story, Krakauer wrote and published the book Into the Wild in 1996 about McCandless’ travels. The book was adapted into a film by Sean Penn in 2007 with Emile Hirsch portraying McCandless.
