Grouse Creek Trail from the Main Boulder (east trailhead) Main Boulder Valley Professional Review and Guide
"The east end of the Grouse Creek Trail begins from the historic Main Boulder Ranger Station in the Gallatin National Forest. The restored pine-log station, built in 1903, is among the oldest continually used forest service facilities in the nation. From the ranger station, this hike gains substantial elevation up the west flank of the main Boulder canyon, heading up to the scenic plateau between the main Boulder and West Boulder drainages. Near the top, the trail climbs over a saddle between Baker Mountain and Mount Rae to Burris Flat, where the open grasslands allow for expansive views. The path continues across the plateau to Nurses Lakes, a series of eleven shallow tarns, then descends into the West Boulder by the West Boulder Campground."
