Mars Plume

Are people aware of this "cloud" phenomenon?

Yes and it got buried in another topic off the active list already.

Mars express in the unmanned topic area

Wow dates to about the time of the crash so I am surprise that its still intact...

This week, the European Space Agency released a picture taken by its Mars Express orbiter that showed what it described as “a curious cloud formation” stretching from east to west near Arsia Mons, the southernmost in a string of three volcanoes.

Suspended over the western slope of Arsia Mons, an enormous volcano near the red planet’s equator, the elongated cloud stretches for about 930 miles

What's That Weird Cloud That's Been Looming Over Mars for Weeks?

With its 12-mile-high peak and diameter of nearly 400 miles, Arsia Mons is 30 times more voluminous than the largest volcanoes on Earth. Its humongous bulk condenses and cools air currents as they pass over the summit, creating this “orographic cloud”—a nephologic formation that tend to form over leeward (downwind) slopes—on the western flank of the volcano.

Similar clouds observed in 2009, 2012, and 2015 coincided with the winter season, so it’s not surprising that this one showed up a few weeks before the Martian winter solstice on October 16. Plus, Mars was recently gripped by a dust storm that encircled the planet in June and July that likely boosted the cloud’s visibility and size.

Wow 4th times a charm ....

sounds like the perfect place to land near....

I made note that tectonic drift was simular to the Hawian island ....

Re: Mars Plume

Venturing a guess, the recent dust storm temporarily raised the humidity.  At night of course it would be frost, and then humidity again the next day.  If so then this cloud should go away as the water migrates back to the polar caps.

Done.
