This species is found from southern British Columbia through western Washington and Oregon into northern California. Only two records have been obtained from the park. These came from a specimen trapped at Bear Prairie (2,000 feet) about three miles south of Longmire and from one taken in Stevens Canyon (no elevation given). The wandering shrew lives in areas where there is considerable moisture and a damp, heavy forest cover. The Olympic dusky shrew, _Sorex obscurus setosus_ Elliot, is a fairly large shrew with upperparts brown with a few light-tipped hairs, the lower parts ashy washed with buff. The tail is brown above and yellowish-white below. This shrew is found from the Cascades westward and south as far as the Columbia River. In the park it has been recorded in a number of localities ranging from 2,000 to 6,800 feet in elevation. It is normally found in moist situations where the undergrowth is heavy and is one of our common shrews. The cinereous shrew, _Sorex cinereus cinereus_ Kerr, is of medium size and difficult to separate from the dusky and wandering shrews. It is distinguished by its small size and pale color. This species “ranges over most of Alaska, Canada and the northern half of the United States” (Dalquest). Within the park it has been recorded only along the Paradise River, and data are lacking regarding its range. The Trowbridge shrew, _Sorex trowbridgii trowbridgii_ Baird, is a large shrew, about three-fourths the size of a common house mouse. In coloration it is black or grayish above, lighter below. The tail is sharply contrasting blackish above and whitish below. This shrew is found west of the crest of the Cascade Range in Washington and Oregon, and has been collected in the park at Ohanapecosh (2,000 feet), Tahoma Creek (2,500 feet), and Longmire (2,700 feet). It prefers dark woods and moist situations. The navigator water shrew, _Sorex palustris navigator_ (Baird), is a large shrew about the size of a house mouse, with small fore feet and broad hind feet. Its coloration above is dark brown or blackish with some of the hairs whitish tipped, the underparts are whitish-gray. The tail is brown above and pale gray below. This species is found from the Rocky Mountains and the outlying ranges of British Columbia to southern Colorado, and in California as far south as Sequoia-Kings Canyon National Park. It is commonly encountered from the lowest elevations in the park up to around 8,000 feet, and is usually found along stream banks and at lake outlets. The Bendire water shrew, _Sorex bendirii bendirii_ (Merriam) is about the size of a house mouse, a sooty-gray color above and slightly paler below.
