The ascent towards Everest Base Camp continued through Alpine meadows and summer yak pastures towards the end of the moraine of the Khumbu Glacier.
I was personally touched by the monument raised for Scott Fischer as I read the book “Into thin air “ prior to leaving for Nepal.
From the top of the hill, we could see where Everest Base Camp is located….at the end of the Khumbu glacier. It looks smooth from here but it’s anything but….
Moraine is the general term for debris of all sorts originally transported by glaciers or ice sheets that have since melted away.
When a valley glacier melts completely away the debris carried on or within it are dropped on the valley floor, forming a deposit called ground moraine.
