In post one, I showed two photos of a glacial lake appearing quite different in the morning and the afternoon from the same location.
The two photos below were both taken in the morning. The first one was shot at 7:13 AM right on Lake Louise, and the second one was shot at 7:34 AM as I was little ways up the trail to the Beehive. Once again, we see the glacial lake appearing as a mirror and then appearing as an emerald sheet.
The questions now are: Why does the Lake look different in these two photos? How does this explanation compare to your explanation for post one?
