Moose Tracks started from the valley floor! I'm not aware of any routes that continue up either of those canyons, but it's possible. No water, either. Nice views though.
The Silver Canyon road, from the Law's Museum area, goes all the way up to the crest, but involves several stream crossings.
From the crest follow the road North toward WM Peak. As with the paved road, snow can make this approach quite a slog near the top. Four wheel drive, high clearance recommended.
Another approach, via Black Canyon road, goes all the way up to the Schulman Grove area. It starts just South of Bishop, off the Warm Springs road. Four wheel drive, high clearance is mandatory, along with experience in that kind of terrain. I did this several years ago and had to do my own road repair work (!) on the way up, driving a Toyota Land Cruiser.
Or...he could drive up HWY 6 and do the hike to Boundary Peak and stop at the snow line.
Keep monitoring road conditions from the White Mountain ranger station 'phone number. Maybe conditions will improve after this storm passes.
A few nights in a hotel at Mammoth Mtn. (9,600 ft) might be much easier.
