Rosalie Peak

From the Deer Creek Trailhead, start hiking on the Tanglewood and Rosalie Trails. Follow the Tanglewood (#636) and Rosalie (#603) Trails west to a junction near the start with a trail that heads up Deer Creek.The Rosalie Trail bears left up an old logging road, while the Tanglewood Trail goes right. Again, take the right fork here, and stay on the Tanglewood Trail. Stay on the main trail as it heads toward West Pegmatite Point.4 miles from the Deer Creek Trailhead, you'll gain the saddle between Rosalie to the left and Pegmatite Points to the right. Once you gain the saddle, you'll leave the trail and go to the west.The trail you were on becomes the Roosevelt Lakes Trail and continues to the Roosevelt Lakes below. No trails are going up from this point, but another 1600' of tundra are between you and the summit.Approach Rosalie's false summit -The hardest point on the ridge is just before the false summit. From the false summit, you can view the true summit. The summit is mostly flat.Return the same way you came.
