Bull elk are the most polygamous of all deer. During the mating season, which occurs late in the fall, a single bull will gather together a “harem” of from three or four to as many as two dozen cows with the current year’s calves, and defiantly assert his mastery over the group, driving away younger bulls of lesser strength. Should another bull challenge his dominance, the ensuing battle is rarely fatal, although it may result in a new master. It is not unusual to see the loser, reduced to the status of a “bachelor bull,” ranging alone. The “bugling” of the bulls, a shrill, high-pitched invitation to combat, is a thrilling call, an unusual record of the music of nature. The young are born in late May or June, usually one to a mother, sometimes two, and rarely three. Like all deer, they are spotted, somewhat lighter in color than the fawns of the black-tailed deer. The spots are retained until replaced by the winter coat. CASCADE MOUNTAIN GOAT, WHITE GOAT, MOUNTAIN GOAT _Oreamnos americanus americanus_ (Blainville) The goat is completely unlike any other park animal, and is easily identified by its resemblance to a large white or yellowish-white domestic goat. Both sexes have short, black, sharp-pointed horns, and are otherwise alike, except that the males are generally somewhat larger, and have a distinct beard. _Specimens in park collection:_ None. The Cascade mountain goat is found in the Cascade Mountains of Washington. Records indicate that it probably ranged into the Oregon Cascades some decades ago, but there are no recent authentic reports from that area. Sub-species similar to the Cascades goat are found in the northern Rocky Mountains, northward through Canada and into Alaska, as well as on the Olympic Peninsula. [Illustration: The mountain goat is an indomitable mountaineer.] In the park in summer this denizen of the rocky crags is rather frequently seen in the high country on all slopes of the Mountain. The principal bands may be found in the region of Van Trump Park, Cowlitz Rocks, Cowlitz Chimneys, Steamboat Prow, Burroughs Mountain, the Colonnade, the Puyallup Cleaver, and Emerald Ridge, where they normally range at elevations of from 6,000 to 10,000 feet. In winter it is not uncommon to observe small bands on Cougar Rock, the southern slopes of Tum-Tum Peak, Mount Wow, lower Emerald Ridge, Mother Mountain, and the western slope of Chenuis Mountain.
