Here is a pic of a typical cache. Caches need to be buried deep in the snow with at least a meter of snow on top to prevent the ravens and/or the wind from un-burying it.Nate Opp Called in today from the other side of Windy Corner. They were able to put their cache in today. He said that the travelling conditions and weather are excellant right now. They are doing well and are hoping to move up to 14K camp tomorrow weather permitting.
