What risks did Jim Gallien notice that Chris was taking when he dropped him off on the Stampede Trail just north of the Denali National Park? Why did Gallien decide not to stop in Healy to notify the Alaska State Troopers about McCandless’s plans?

1) Alex's backpack appeared to weigh only 25 or 30 pounds, which struck Gallien, an accomplished outdoorsman, as an improbably light load for a three-month sojourn in the backcountry, especially so early in the spring.

2) Gallien was concerned: Alex's gear seemed excessively slight for the rugged conditions of the interior bush, which in April still lay buried under the winter snowpack.

3) Chris admitted that the only food in his pack was a ten-pound bag of rice. He had no compass; the only navigational aid in his possession was a tattered road map he'd scrounged at a gas station, and when they arrived where Alex asked to be dropped off, he left the map in Gallien's truck, along with his watch, his comb, and all his money, which amounted to 85 cents. "I don't want to know what time it is," Alex declared cheerfully. "I don't want to know what day it is, or where I am. None of that matters."
