Strange show spotted high above Mars’ surface remains mysterious

Strange show spotted high above Mars’ surface remains mysterious
Amateur astronomers saw it, professional astronomers aren’t sure what it
was.

Almost three years ago, the Red Planet put on a bit of a show for
anyone with a telescope big enough, and an eye trained enough, to
spot it. As the Terra Cimmeria region of Mars’ Southern Hemisphere
rotated into view, a faint bulge rose above the smooth curve of the
planet’s surface. It looked like a cloud, but it was too tall and too
weird.

Starting on March 12, 2012, amateur astronomers reported seeing the
odd lump on the Martian horizon. Reports continued to pour in over
the next 11 days as the lump became even more obvious. It petered out
some time before April 1, but a second occurrence was observed
between April 6 and April 16. Each time, its form varied from day to
day, and it was seen as dawn swept across the region—but not at
dusk.

Let's see... dawn occurs at the end of the night, and night is when there is no sunlight and ice can form more easily. Dusk occurs at the end of the day, and day is when there is sunlight and ice can vaporize more easily.... hmmmm.

Of course, the CLIMATE MODELS, which we are apparently to always take as gospel, say it can't be ice...hmmmm.
