Silver Lake is a snowbound Colorado resort town and the setting of the Lakeside Resort chapter, where Ellie is playable for most of the winter. A group led by David lives here. Its surroundings include an abandoned coal mine and the Whitefish Lake rest area.
The chapter opens with Ellie hunting a deer with her bow while Joel lies feverish in a house. She trades the deer to David and James for medicine, and the pair hold off a wave of infected together in a warehouse. Later, Ellie escapes into a blizzard with only her switchblade and must take a pistol and ammo from enemies.
David's group survives by eating people. They use a converted butcher shop to store and prepare bodies, and Joel finds corpses hung upside down while he searches for Ellie. Some residents grumble that David's leadership should be put to a vote again.
Ellie's final fight with David happens in the town's intact restaurant, where broken plates on the floor let him hear her moving. The building catches fire during the struggle, and Ellie kills David with a machete just before Joel reaches her.
