Difficult to distinguish from other mice and vole species without close examination of teeth. Usually dingy brown and gray with coloration lightening with age. Habitat preferences are damp fields as they do not do well without moisture.
Large claws for digging and small eyes and ears characterize this vole. They have smooth fur that reduces friction underground and are gray and brown with pale gray undersides. They cover a wide variety of habitats within their range but spend a majority of their time in underground tunnels that they dig.
