California does eerie especially well.

From desert ghost towns and artist-built cults to gilded-age poisonings and true-crime mythologies, the West’s darker corners have long inspired both fear and fascination. This Halloween, we’ve collected eight Alta stories—true tales, essays, and reported features—that explore the strange, haunted, and often beautiful intersections of California’s past and present.

There’s a marshmallow laced with strychnine. A haunted house that doubles as immersive theater. Ghost towns where the real hauntings might be economic. And at the center of it all: a state that never quite lets its weirdest stories go quiet.
