Optical illusion -- 2
Second of two photos -- the other partly overlaps this one. Both are in the album "Utah".
A crust formed atop the sand, presumably from being wet, then the wind broke through in places and excavated the sand. To my eye, this is a persistent optical illusion. The deeper orange areas can be seen either as depressions (the correct view) or as low mounds, which makes it hard to make sense of the image. This was close to a steep bank, and the light is mostly coming from the left.
Weirdly, at least to my eye, it's easier to see the correct view in the thumbnail than when expanded. And it's easier to get the correct view in the other photo.
