High above Nesada point rests Zatten Glacier, a slow moving glacier that has been sitting there for thousands of years. There is a point when the trails run out and the tree line dies out and it is just pure snow and ice, little to no life to be found. The only cool features the glacier has, should you travel high enough, is the ice caves. There is a large cave system stretching for miles that is made out of pure ice and is colored different shades of blue. You might find something interesting in them, should you dare to travel that high.
