Fig. 24.—Distribution in Colorado of jumping mice (genus Zapus). Blanco County, state that during the haying season jumping mice are often seen in the meadows bordering Wliite River. The vertical distribution of this species is indicated by* specimens from Meeker (6,000 feet) and Arapahoe Pass (over 9,000 feet). Erethizon epixantlium Brandt. Yellow-haired Porcupine. Yellow-haired porcupines are more or less abundant throughout the mountains, but are most often seen in the coniferous forests of the Canadian zone. They occur regularly to timberline, and in the Grays Peak region are said to be found occasionally among the rocks far above the limit of trees. They are reported sparingly from the 3^eUow pine belt of the eastern and southern foothills, and even.
