In "The Outcasts of Poker Flat" what happens to the travelers at the camp?
The shortest answer possible to your question is this: all but two of the travelers die at the camp.
The travelers that wind up at the camp are John Oakhurst, Mother Shipton, Duchess, Tom Simson, Piney Woods, and Uncle Billy. John Oakhurst had wanted to push on through the day and make the next town, but the group forced him to rest with them. That was a mistake, because a storm came up and snowed them all in . . . except Uncle Billy. During the night, he stole the group's horses and supplies. After 10 days of being snowed in and starving, John Oakhurst told Tom Simson to take the rest of the supplies and go back to Poker Flat and bring help. By the time help arrived, Mother Shipton, Duchess, and Piney had either frozen or starved to death. John Oakhurst shot himself.
