Above LBSL you will be melting snow for water. There are a couple of places where you can get water during the day: the stream is exposed near Clyde Meadow, and there were rocks with small pools of water (during the warm part of the day) below Iceberg.
If I had know about the snow block shelters below Iceberg (above where we camped last weekend), I would have stayed there. Camping at Iceberg means you have to hump your gear over the cliff below, and I didn't notice any place to get out of the wind up there. The rock shelters are still under a couple of feet of snow.
