The Plateau Deermouse is one of the largest species of Peromyscus , with dorsal pelage varying from ocherous to gray, brown, yellowish, or cinnamon. Variation in coloris related to substrate on which they live, being darker where dark volcanic soils are present. Venter is cream white, with plumbeous hairs showing through. Feet are white.

They prefer rocky soils and build their nests at bases of plants. Food and Feeding. Plateau Deermice are granivores and eat seeds of many plant species. Breeding. Reproduction occurs in February-March and June-October. Litters have 2-5 young. Activity patterns. The Plateau Deermouse is presumably nocturnal. Movements, Home range and Social organization.
