Yes, you are correct Mike.

The difference between normal shadows and the refections are that the reflection will show different shades and is much more accurate with the tints - so it is not a shadow. (ook at the next set of ridges below)

Only the small hills near the lake edge are reflected - the creeks above are not becaue they are set too far back as in normal reflections - BUT if you take the mirror image of the creeks below the first cliff line you get the reflection of everything below and it is quite accurate. Therefore, the dark spots below ARE reflections.

Same on the right hand side, except each ridge line above the lake is reflected in the lake as a different color (we can only see black and white shades though).

To the amateur it just looks like a set of dark rings, but the details are quite accurate. I suggest you take each feature and look for its opposite image - then one quickly picks up all the changes and the headings of all the creeks. The image is lost as you go further down due to
the pixel size but also because there is nothing to reflect.

Shadows do not show up this type of thing. I am convinced of that, I went outside and looked for ages to find an example which showed it this clearly, but couldn't.
