An isolated dune on Mars
Cool image time! The image above, cropped and rotated to post it here, shows a single isolated large dune inside an unnamed crater on Mars. The image was taken by Mars Odyssey on June 5. To the right is a close-up of the dune itself. Its isolated nature as well as the darkness of its sand in comparison with the surrounding territory has probably got some planetary scientists scratching their heads. Furthermore, the darker streaks that appear to flow down the dune are quite intriguing. Were they formed by briny seep water, as has been found with other seasonal dark slope streaks? Or are they evidence of sand avalanches?
I imagine that there will be an effort to monitor this dune over time, to see if it changes.
Readers!
My annual February birthday fund-raising drive for Behind the Black is now over. Thank you to everyone who donated or subscribed. While not a record-setter, the donations were more than sufficient and slightly above average.
As I have said many times before, I can’t express what it means to me to get such support, especially as no one is required to pay anything to read my work. Thank you all again!
For those readers who like my work here at Behind the Black and haven't contributed so far, please consider donating or subscribing. My analysis of space, politics, and culture, taken from the perspective of an historian, is almost always on the money and ahead of the game. For example, in 2020 I correctly predicted that the COVID panic was unnecessary, that the virus was apparently simply a variation of the flu, that masks were not simply pointless but if worn incorrectly were a health threat, that the lockdowns were a disaster and did nothing to stop the spread of COVID. Every one of those 2020 conclusions has turned out right.
Your help allows me to do this kind of intelligent analysis. I take no advertising or sponsors, so my reporting isn't influenced by donations by established space or drug companies. Instead, I rely entirely on donations and subscriptions from my readers, which gives me the freedom to write what I think, unencumbered by outside influences.
You can support me either by giving a one-time contribution or a regular subscription. There are four ways of doing so:
1. Zelle: This is the only internet method that charges no fees. All you have to do is use the Zelle link at your internet bank and give my name and email address (zimmerman at nasw dot org). What you donate is what I get.
2. Patreon: Go to my website there and pick one of five monthly subscription amounts, or by making a one-time donation.
3. A Paypal Donation or subscription:
4. Donate by check, payable to Robert Zimmerman and mailed to

Perhaps it is material welling up from a deeper strata that was opened by the impact? Sand bearing briny water perhaps?
A water volcano!
Beautiful curves! Like a flower, a rosette on Mars.
Maybe it is seasonal how the wind direction changes there? Gradually around.
Reminds me of the Paha of the midwest

Looks like a massive Martian trilobite! ;)
(Seriously, nice image.)
