Could well be Sorbus sitchensis, Stig. Can be 1-20' tall, depending on the conditions. A cut and paste blurb:
Sitka mountain-ash berries remain on the trees until late winter, making
them available as winter forage. They are important in the diet of many
upland gamebirds, songbirds, and small mammals [14,26]. The twigs
supply browse for deer and moose [14]. Roosevelt elk also utilize Sitka
mountain-ash in the summer months [19]. Black bear and grizzly bear eat
the berries, leaves, and stems [21,27].
