The birds of the Raft River Mountains, Northwestern Utah

As another facet in a long-term analysis of the birds of Utah, an avifaunal survey was made in the northwestern corner of the state. Here the principal physiographic feature is the Raft River Mountains. The main axis of this range runs in an east-west direction paralleling the Utah-Idaho border immediately to the north. To the southwest lie the lower and less prominent Grouse Creek Mountains and in the extreme northwest corner of the state there is another, smaller range, the Goose Creek Mountains. The Grouse Creek Mountains run in a north-south direction, while the main portion of the Goose Creek Range runs essentially northeast and southwest and then tails off to the south along the Utah-Nevada border. Just west of the Grouse Creek Mountains is Grouse Creek Valley, which runs north and south in Utah parallel to the Utah-Nevada border. While nearly all parts of the region were visited, the Raft River Mountains received most of the attention, especially the north slope in the vicinity of the towns of Yost, Standrod, and Nafton.
