The feet are much darker and the dorsal surface of the tail has more black. The overall appearance of the pelage in winter is similar to that of the summer pelage west of the Cascade Range but are grizzled. In summer, the pelage is much lighter black bands on hairs are shorter.Įast of the Cascade Range, the light-colored bands on the dorsal hairs are almost white instead of buff and the dark-colored bands are much narrower. Overall, the coloration is dark buff shading to black on the dorsum. The feet are mostly white with splotches of buff dorsally.
