Dune-like formations, pillows, and fresh cornices are all visual clues the wind has been affecting the snow. Use small test slopes to look for signs of cracking as evidence that you should avoid steeper and more consequential slopes. Use extra caution around slopes leading into terrain traps, which could injure or bury a rider.
In many locations, the most recent snowfall is resting on a smooth crust, which provides an excellent bed surface. The new snow needs time to bond to the old snow interface. Although it may be difficult to find there are pockets of buried surface hoar beneath the snow that fell the night of 1/11.
