Hauser, Solar, Fort, and Rainbow Lakes Loop Professional Review and Guide
"Hauser, Solar, Fort, and Rainbow Lakes rest in the heart of the Beartooth Plateau across the road from Long Lake. The four alpine lakes sit above 9,600 feet in rock-studded meadows amid forested knolls, meandering streams and pools, and abundant wildflowers.
Small pines and firs, scattered granite rocks, and alpine tundra surround 1 8-acre Rainbow Lake, the largest of the four lakes. Throughout the hike are vistas of Beartooth Butte and scalloped Sawtooth Mountain. The hike begins at the Hauser Lake Trailhead on the southwest end of the Beartooth Loop National Recreation Trail (Hikes 39 and 40), then explores the four lakes across the trail-less, open tundra."
