Walking on top of a glacier reveals so many surprises [and thankfully on this day, no crevasses].
There are rivulets on top of the glacier where the ice melt courses down. The channels wear away at the ice, in places they almost collide, leaving thin little ice walls that are made translucent in the sunlight. It is so easy to get lost in the beautiful colours.
In places the ice will push up in these little [or not so little] mounds.
And of course, there is the surprising rusted iron in the stones, creating startling bursts of orange.
