It turns out that glacial lakes are cold, really cold. Not that I noticed right away. I was wearing hip waders so I could stand thigh-deep in the just-above-freezing Hooker Lake while shooting icebergs and Mt. Cook at sunset. Because I wasn't wet, I didn't feel the cold right away. No, it was only after I'd been standing in the water for 40 minutes then tried to move that I felt it. My legs had turned to cold iron, and I could practically hear the creaks as I willed them to move back up to dry land. All in a day's work, and well worth it for a sight like this one.
