To understand this story, you have to listen to this camper first.
His story is loosely based on real life event, a group called the Donner party was traveling west. Just like the one in the game, the donner party also got caught up in bad weather.
Many of its members died and some resorted to Canibalism, a newspaper article also mentions this incident.
An abandomed wagon train east of lake Isabella, and a cave with human remaining nearby.
It is the location of the abandoned wagon train.
The Real life donner party's wagons were Ox-Drawn. That's why you can find frozen cattle here, instead of frozen horses.
After the cattle was too weak to pull the wagons, the families left it there and tried to find the shelter.
You can find the cannibal cave here.
This skeleton most likely belongs to the last person that died. You can find bones lying around, the little food supply that they had is also some.
The members of the donner party also died near a lake, It was later named donner lake.
Unlike in the game, there were people who survived the real life event. Out of that group, a woman named Isabella lived the longest, she was one year old at the time of the incident.
The developers might named this lake Isabella as a tribute to her.
