What possessions does Alex take with him into the Alaskan Bush?

In "Into the Wild," Alex (also known as Christopher McCandless) takes minimal possessions with him into the Alaskan bush, including a backpack, a rifle, a small amount of food, a map of the area, a journal, and a few basic camping supplies. He deliberately travels light to embrace his ideals of self-sufficiency and simplicity. His journey reflects his desire to disconnect from society and seek a deeper understanding of life in nature.
