What is the main conflict in Two Old Women: An Alaska Legend of Betrayal, Courage, and Survival by Velma Wallis?

The People are a tribe of Native Americans who live north of the Arctic Circle. This particular winter, The People are struggling to find enough food to avoid starvation. The Chief announces one day that it is time to move on in search of caribou, but this time they must leave behind two old women because they have become a drain on The People. These two old women, Sa' and Ch'idzigyaak, cannot believe that they are to be left to the mercy of the elements around them. Ch'idzigyaak especially, because she has a daughter and grandson in the tribe, is hurt beyond description. Before The People move on, Ch'idzigyaak's daughter gives her a babiche, and her grandson leaves his hatchet with her.
