Answer:
Find the explanation below.
Step-by-step explanation:
After arriving in the Alaska bush in April, McCandless attempted returning back to civilized life in July but unfortunately for him, the Teklanika river through which he entered the bush was now covered with Cantwell Glacier, a kind of snowmelt that made the river impassable.
He did not have sufficient food provisions to last him during his stay neither did he have a good map and adequate information of the geographical location he was sojourning to. If he had these pieces of information, he might have known of a cable car that would have crossed him through the river. He had no choice but to go back to the bus where he dwelt, and there, he died of possibly, starvation.
