These are gorgeous pictures.
If rays from the sun are deflected downward by the mountain's knife edge, wouldn't their light appear to come from higher up in the sky, rather than from lower down?
All a fine 2016,

Dear Roger,
Your Mount Baker pictures are indeed a
feast for the eye.
Did Barry Barry Duell explain the physics
in his talk on the Fuji Diamond?
The sun appears "to take a bite out of"
Mount Baker and my inference is that this
is an example of Knife-Edge Diffraction
as explained by Huygens and Fresnel.
I should be interested to hear whether
this is right. Should one expect a
slight change in colour between the sun
ABOVE the bite and IN the bite?
Very best wishes
Frank
