“If then, the Powers-that-Be have allotted to the Marmot five full years of life, and he elects to live that life in ten bright summer times, then must he spend the six dark months each year in deathlike sleep. And this he does, in calm, deliberate choice. “Oh, happy Whistler of the Peaks! How many of us would do the very same, were we but given choice.” Not many natural enemies threaten the marmot. Perhaps the most to be feared is the golden eagle, which may drop from the blue to seize him in the midst of his luxurious sun-bath. Because of his size the smaller predators are harmless to him, but the coyotes and foxes are relentless hunters and ever-present dangers. THE CHIPMUNKS Two kinds of chipmunks, the Cooper and Hollister, are known to occur within the park. Although their altitudinal ranges overlap, the two species may be quite readily distinguished by their variation in size and other characteristics. A brief discussion of each follows: [Illustration: The Hollister chipmunk is a lively and audacious little animal.] The Cooper chipmunk, _Tamias townsendii cooperi_ Baird, is the larger of the two species mentioned above. It is predominantly dark brown in color; the light colored stripes above and below the eye are indistinct; the black head stripes are not conspicuous; the nine alternating black and grayish white lengthwise stripes on the back are somewhat obscured by the dark color; the tail is black above, grizzled with white, silvery margined, reddish brown below. The total length of a typical specimen is ten inches; head and body, five and one-half inches, tail four and one-half inches. This chipmunk is found in the higher eastern Cascade Mountains and Olympic Mountains of Washington. In Mount Rainier National Park it occurs from park boundaries to 6,000 feet, almost to forest line. The Hollister chipmunk, _Tamias amoenus ludibundus_ (Hollister), also called the little chipmunk or Alpine chipmunk, is about a third smaller in size than the Cooper chipmunk. It is predominantly gray brown in color. The light colored stripes above and below the eye are distinct; the black head stripes are more conspicuous than those of the Cooper, the back stripes are sharply defined; the tail is brown mixed with black above, margined with yellowish brown, yellowish brown below. The total length is about eight and three-fourths inches; head and body four and three-fourths inches, tail four inches. The Hollister chipmunk is found in the higher Cascade Mountains of Washington. In Mount Rainier National Park it occurs generally in the Hudsonian Zone between 4,500 and 6,500 feet, rarely lower or above forest line, but it is one of the few park animals recorded on the summit of Mount Rainier. _Specimens in park collection:_ Cooper chipmunk, RNP-7, RNP-8, RNP-9, RNP-16, RNP-18, RNP-74, RNP-110; Hollister chipmunk, RNP-28, RNP-29, RNP-30, RNP-95; Longmire Museum, Park Headquarters.
