Alpine Chipmunk records in California fit cool conifer forest, rocky slopes, and mountain meadows.

Reports center on the Sierra Nevada high country, with records separated from California’s hot lowlands. They show where people have documented the species, and they don’t rank California’s best habitat.

Reports rise most clearly in Jun–Sep. That pattern can reflect animal movements, weather, and observer effort, so it isn’t a population count.
