What is on the bottom of that rock?
If you read the link to the very old thread I posted (and if you read a few more posts) you would have seen that it was glass.
I know, your next question would be "Glass? Where would glass come from?"

interesting .. how does water flow , if the atmospheres too thin to support it, would the Martian seasons create denser pockets of air in certain regions allowing the water to congregate/pool on the surface? what would be the sweet spot temperature be to keep it in liquid form ?
and how does water become mineral bound? is that on an elemental level? would be interested to seeing the maths of that

Dark, finger-like features appear and extend down some Martian slopes during late spring through summer, fade in winter, and return during the next spring. Repeated observations have tracked the seasonal changes in these recurring features on several steep slopes in the middle latitudes of Mars' southern hemisphere.
"The best explanation for these observations so far is the flow of briny water

kinda odd this shot. looks like predawn with many artifacts/pinpoints of light , I thought it might be a longer exposure shot and they are stars , but they cannot all be stars , as they extend into the land, peculiar. I don't recognise any constellations either.
PASADENA, Calif. -- Observations from NASA's Mars Reconnaissance Orbiter have revealed possible flowing water during the warmest months on Mars.

The droplets do not look like glass but that is not the reason I am of the belief that there is liquid water on Mars, I believe we do not understand the processes on Mars nor the possible changes that take place in water to remain stable in low atmosphere.

At certain times of year, at Mars locations, you can see the water leaving flow channels (I don't remember the name of any threads or data on this besides recalling the photographic comparisons between the water flow and when it doesn't flow).

Flowing must mean liquid and as it can be seen "flowing" it is on the surface.

indeed , but usually you would leave the lens cap on before taking a bias, do they have that ability on the cam?..
here's a gif illustrating their fixedish position's
Regarding the dark color of the flows, McEwen added, “The flows are not dark because of being wet, they are dark for some other reason.” McEwen also mentioned that researchers will need to re-create Mars-like conditions in the lab to better understand these flows, stating, “It’s a mystery now, but I think it’s a solvable mystery with further observations and laboratory experiments.”
