What mistakes, if any, did Chris make before going to Alaska?

Below you will find two examples from the text:

“He wasn’t carrying anywhere near as much food and gear as you’d expect a guy to be carrying for that kind of trip,” Gallien recalls.

Alex admitted that the only food in his pack was a ten-pound bag of rice. His gear seemed exceedingly minimal for the harsh conditions of the interior, which in April still lay buried under the winter snowpack. Alex’s cheap leather hiking boots were neither waterproof nor well insulated. His rifle was only .22 caliber, a bore too small to rely on if he expected to kill large animals like moose and caribou, which he would have to eat if he hoped to remain very long in the country. He had no ax, no bug dope, no snowshoes, no compass. The only navigational aid in his possession was a tattered state road map he’d scrounged at a gas station.
