Let's see. Yes, there are distinct avalanche zones along that route. Skiers have died. Make sure that you have wide climbing skins with good adhesive. The weather tends to be fairly bad up there, and you just can't afford to be fooling around with skins that don't stick right.
First, I will assume that you are starting near Lake Mary on Old US 40, the Old Donner Pass Road. I make that assumption, because there isn't any good place to park at all. We used to get there early in the morning, whip out about three snow shovels, and dig a car-size hole in the nearest snow drift, making sure to get the tires off the pavement. You ski across Lake Mary and continue southbound across the low contours of Judah Ridge, and just barely avoid the downhill ski runs (go higher). That heads you up to the first steep slope that connects Judah Ridge with the saddle toward Mount Lincoln. Contouring that slope is one of the first nasty areas. That gets you to the saddle. Continue as if you are heading up Mount Lincoln, except that you stay just outside the downhill ski area. If the east face of Mount Lincoln has any deep snow, that is the the big nasty area. It slides routinely. Instead, stay off the steep area and continue directly to the Mount Lincoln summit where the ski lift empties and there are downhill skiers around. If you attempt to leave the roped off summit, the ski patrollers might hassle you. Instead, if you stay outside the roped off area, you are not their responsibility and you should be good. If they do hassle you, you just tell them that you have a reservation for Benson Hut, point south, and then go.
You follow the Sierra Crest south for several miles, always staying within 100 yards of the actual crest. There used to be a series of wooden trail markers on trees all along there, and each marker listed the bearing and distance to the next marker. There is often a cornice along the actual crest, which is why you don't want to get too far that way to the left. Plus, if you get too far down into the trees to the right, it is harder. Just follow the crest out until it starts to rise toward Anderson Peak. Benson Hut sits just below timberline on the north side of the peak, and it has a great view to the east. This year, it appears that the snow won't be too deep, so you ought to be able to find the hut, and its outhouse is just west of it near the trees. The bunks are downstairs, and there is flat floor space in the attic.
It is normal to enter by the attic window, climb down into the hut, open the front door, and then shovel your way out.
From the hut, the logical direction to go is south toward New Bradley Hut, and that's a problem. There are three route possibilities. One is to try to cut directly across the east face of Anderson Peak. I've done that, and I don't recommend that because of avalanches. The second is to cut all the way around the west side of Anderson Peak. I've done that, and I don't recommend that if the wind is blowing. That west slope slides also. The third way is to ski and climb up the narrow chute on the north side to the Anderson Peak summit. It's a lot of work, but we have found it to be more predictable. From Anderson Peak, you can continue to follow the crest south toward Tinker Knob. From there, you have to decide whether to cut southeast toward New Bradley Hut, or to continue south toward Squaw Valley.
We used to do this a lot as a three-day trip. One day got us to the hut. The second day, we would ski to the hill overlooking Squaw Valley, eat lunch, and then ski all the way back to Benson Hut. Then the third day, we would head back out to Lake Mary to the cars. We did this trip a couple of times when the weather was so bad that they had closed Mount Lincoln for downhill skiers.
MORE: Coldstream Canyon is somewhat northeast of Benson Hut. Supposedly there is a route through there to the hut which can be used in bad weather. I've skied into the canyon far enough to see up to Anderson Peak, but it looked nasty to try to work up the east face of the Sierra Crest. At the hut, there is a map which shows the canyon route for escape purposes.
