LOL, I know what you mean! The people commenting on that story mentioned contamination by terrestrial methane, but they overlook the presence of methane in samples taken directly by the Rover, in situ. Nice link, Cruisedad, thank you!

The ESA story was particularly interesting to me. They mentioned that vulcanism has not been directly observed yet on Mars--I wonder what theories they might have to explain the plumes that have been imaged in the last few years. Is there such a thing as "explosive sublimation"? Many of the plumes seem to contain something that is dark-colored--who knows if it's soil or a byproduct of biology? Thank you Todd!

There are plumes that have been observed but not yet attributed to any cause.

It seems likely related to the cloud phenomena which could be CO2 and water vapor.

Mars has not had major volcanic activity for 100-150 million years but smaller isolated eruptions may have happened within the last 2 million years.

Thank you to everyone who has stuck by the YouTube channel and to all of our admins and forum users here on the channel.   They really have kept the website current while I have been busy taking care of things in my personal life.   I promised that the next video would be a long one and have a LOT to look at.  You can get lost in these Gigapans and I really hope that you do!  I spent a lot of time stitching these together and making sure that they were the best quality that I could get them.  SOL 1448 really has been a goldmine for anomaly hunters and those people who are just hobbiest.  I really hope you enjoy this one and expect much more to come from the latest batches of images!
