MAMMALS. 51 ordinary woodcliuck and Aary in color from a yellowish brown inmidsummer to a light gray winter coat in fall and spring. The head,feet, and tail are always dark, but a white band around the nose infront of the eyes is usually a conspicuous mark, even at a distance. They live mainly in the Hudsonian Zone, but often range over theopen slopes of the Arctic-Alpine above the extreme limits of timber-line. Apparently they fill the whole Hudsonian Zone area of theGlacier Park region and may be seen on every high pass over whichtrails lead. They are common at Cracker and Iceberg Lakes, overGunsight, Piegan, Swiftcurrent, and Kootenai Passes, and on theridge at the head of Kintla Lake. They extend also north throughthe Canadian Rockies and south to the Bitterroot and SawtoothMountains of Idaho, while closely related
