Rajan,
{Re: Those are peaks protruding from the glacial ice and are called Nunataks.
There is virtually no human presence here (hiking is the only mode that gets you close to this glacier and it isn't a trivial trek).}
I've seen similar forms in Hawaii, but instead of snow coloring it white there's sulfur coloring it yellow. Sorry I don't know a Hawaiian name for it. It's also a treacherous place. The bottoms of your hiking boots get hot and begin to melt.
