Root Glacier

What are you boys doing way down there? 

Throwing rock in the moulin by chance?

This is an excellent sample of glacier mice.

Below from the Science Nordic article:

Egg-shaped moss balls occur on some glaciers throughout the world, mostly documented in Iceland, North and South America and the Himalaya.

They form when moss begins to establish around a clast (sediments) lying on the glacier surface. The moss continues to grow and insulates the glacier surface, resulting in the moss becoming elevated on a pedestal as the surrounding ice melts. Eventually, the moss falls from this pedestal and may be transported on by wind.

We spent the entire day out on Root Glacier exporting with our guides from St. Elias Alpine Guides and four other tourists.  It was a perfect day with some sunshine, a few drops of rain, and a warm breeze blowing over the glacier.  We could not have asked for a better day to adventure on a glacier!
