Our group of 9 left the Portal around noon on Wednesday. 6 of us reached Trail Camp around 6pm. The wind had calmed down and it was calm all night. Overnight lows were around 25 degrees.
There are patches of snow between Outpost and Trail Camp, but nothing that requires crampons. There is however one traverse just before Trail Camp that requires careful maneuvering.
Trail Camp is snow free and the lake is largely ice free.
Past Trail Camp it's all snow. The switchbacks are largely covered in snow and ice. Around switchback 15 most hikers traverse the snow field and head towards the the snow chute. We hiked up to the cables. Most of us turned around glissading down the slope, while 2 guys continued up the switchback which very few hikers have done since the Memorial Weekend storm.
The chute is the way to go. We have met hikers that have summited without crampons, but it is very foolish to attempt anything past trail cramp without them. The Snow is very soft and melting quickly.
