Final answer:
Chris McCandless set up camp in the Alaskan wilderness after leaving Salton City, which is noted in Jon Krakauer's 'Into the Wild'.
Step-by-step explanation:
In Into the Wild by Jon Krakauer, Chris McCandless set up camp in the Alaskan wilderness after he left the post office in Salton City, California. McCandless ventured into the wild to live a life of solitude and self-reliance, an experience that Krakauer narrates with rich detail and reflection on McCandless's motives and character traits. Drawing parallels to Henry David Thoreau's Walden, Krakauer explores themes of societal drop-out and the search for a meaningful life.
