Hiked from TH to summit via the standard trail over Flat Top's summit (1:30 hrs). Couldn't tell where Flat Top's summit actually was, so I cut off from the trail junction to climb Hallet (2-2:30), and then back across the plateau to climb Ptarmigan Pt (3:00) before descending, with a RT time of 4:20 hrs. Nice trail!
Easy, straightforward route -- though we violated smudge's instructions and had breakfast, not lunch, on top.
Summited Hallet after traversing over Flattop mountain. Enjoyed fabulous weather and views after some tiring postholing below treeline.
