Day 352: Squirrel! You might easily mistake Cascade Golden-mantled Ground Squirrel (Callospermophilus saturatus) for a chipmunk due to its size and lateral stripes. However, the broad, dark saddle and eye ring tell the story. Chipmunks and squirrels are members of the same family (Sciuridae). The easiest way to tell them apart is that chipmunks have a light stripe running through the eye and squirrels have only a ring of lighter fur surrounding it. Ground Squirrel's "racing stripes" may be more pronounced than those exhibited by this individual, giving it an even stronger resemblance to the chips of the area, so check that eye! Both can be very persistent pests in the backcountry, gnawing holes in packs and tents to get at food, or even chewing on sweaty boots and other clothing for the salt.
