Juniperus scopulorum (Rocky Mountain Juniper)

From CONPS: A columnar somewhat rounded evergreen tree. The species name scopulorum, means “broomy,” which refers to the dense sometimes drooping growth of branches. Round, dark-blue, berry-like cones, covered with a whitish bloom, ripen in the second year after pollination. The juvenile foliage consists of pointed, white-coated needles. Adult, scale-like foliage varies in color from dark- to bluish- or light-green. Mature size is from 30-40 ft. high with a spread of 3-15 ft. Bark is reddish-brown or gray and shedding. Several species of birds, such as Townsend’s solitaires (Myadestes townsendi) and waxwings (Bombycillidae spp.), and some mammals eat the berries (seed cones). Sun to part shade, low water use.
