East of Salt Lake City, Utah 150 is known as the Mirror Lake Scenic Byway from Kamas east and north toward Wyoming. Along the way it crosses the Uinta Mountains, the highest east-west range in the lower 48 states. About 26 miles [41.8 kilometers] from Kamas, stop at Trial Lake, at 9,500 feet [2,895.6 meters], to look for mountain birds such as Blue Grouse, Williamson’s Sapsucker, Three-toed Woodpecker, Olive-sided and Hammond’s Flycatchers, Gray and Steller’s Jays, Clark’s Nutcracker, Mountain Chickadee, Brown Creeper, Townsend’s Solitaire, Pine Grosbeak, Cassin’s Finch, Red Crossbill, and Pine Siskin.
In 3 miles [4.8 kilometers], at Bald Mountain Pass, turn toward the parking area for the Bald Mountain Trail, known as a good spot to find Black Rosy-Finch. Check rocky slopes, especially around the edges of ice fields and snowbanks, for this little bird, which nests only above timberline. You’ll also find American Pipit up here at around 10,700 feet [3,261.4 meters]. The 2-mile [3.2 kilometers] trail to the top of Bald Mountain, at 11,943 feet, offers fabulous views of Uinta peaks and lakes. It’s normally walkable only from mid-July to October. In 3 more miles [4.8 kilometers], the Mirror Lake campground and picnic area is another popular birding spot. It is also just plain popular: The parking area here is full nearly every day in summer. After you’ve birded around the lake and picnic grounds, you can walk a short spur trail that leads to the Highline Trail, passing through meadows where you may find Calliope Hummingbird and Mountain Bluebird, as well as forests of Engelmann spruce and subalpine fir where there’s a chance you’ll see Blue Grouse, Three-toed Woodpecker, and other woodland birds. Keep an eye out for Northern Goshawk and Golden Eagle soaring overhead.
