Be aware that my technical terminology in English is not correct, and that my considerations are valid only for the TIMING of my tour. the timing was: - start from trailhead 6.00 am - San Antonio ski hut approximately at 8 am - top of San Antonio at 9.35 - starting descent at 9.50 - car 11.00. Conditions of the snow: Due to the hard snow I didn’t use my skins to ascend , but only boots: without crampons until the hut and with crampons above the hut. - hard frozen crust, in certain points breakable, at the trailhead (Manker Flats) at 6.00 am; - hard and thick crust (never breakable) starting from 200-300 meters above the trailhead; - from the hut I followed the most evident SE slope (the name should be Procrastination Chute). The snow was firm, with only a bit of very superficial softening in certain points of an old avalanche path; - in the last 50 meters under the ridge (I exited on the ridge between Procrastination and Zeke's Chute) there were some consolidated some-days-old wind pillows, recognizable and avoidable, and some cracks. The cracks, actually their visible part, were approximately 5-20 cm deep, 2-5 cm wide, 2-10 meters long. The snow in such part was firm at 9.15 am, and superficially softened (1 cm) at 10.00 am.
