Hiking on an Iceland glacier

I was walking on water. We all were, following our guide. We put our trust in her, that she would keep us safe and that no one would disappear downwards into the blue depths, though she was carrying twenty meters of rope in case we did. I didn’t expect the water to be so blue and so beautiful, though it wasn’t that way everywhere. At one point, our striking blonde guide caught me looking around with a smile.
“Like it?” she asked me knowingly.
I couldn’t stop smiling. “This is really cool.”
