The two pictures immediately above, taken/posted by Philippe are the Main Trail route. The trail is completely buried above Trail Camp until you get over the crest at Trail Crest.
Crampons are particularly helpful to climb the section shown in the pictures. Ice axes are recommended, especially for descending. If that slope ices up (in the afternoon shadows), it can become treacherous.
The NOAA weather forecast (Whitney Weather page above on the left) calls for 20% chance of snow, high of 43F on Saturday, winds 15 mph, Saturday night: 15F. Be prepared!!
Also FYI: There are currently quite a few day hike permits still available online for mid-week hikes through July and August. You might prefer to reschedule and go later.
