Brief report:
Climbed with DeeDee. We started just a few minutes past 7:00AM from Wolverton. Hiked a leisurely pace. Took a snack break at Panther Gap and then another break at the trail junction of Alta Peak & Alta Meadow trails. Then, we went up Tharp's Rock gully (this is a very broad gully due west of Tharp's Rock itself) and on to the summit. Had to put crampons for the last 30 feet to the summit as there was a hard icy layer beneath the 6" of snow. Summited at noon. Fantastic weather (sunny, clear, cobalt blue skies & not even a breeze). Had lunch below the summit and started down at 12:37PM. Back at Wolverton at 3:40PM.
