These look like prime real estate...

Water liquid at Mars' atmospheric pressure?!! This is major stuff in contradiction of what I've learnt as an undergrad are basic laws of science.. Since they took the images, - have you asked NASA/ JPL/ MSSS etc. to comment?

Maybe it is a CO2 fogg

Re: Has anyone else seen these lakes?

*Seems to me they're legit photos with layperson/peoples' interpretation of what the features might be.

Some expanses of sand on Mars do look like water; even down to the ripples.

The assertion of "forest" on the bottom photo's comment strip is a giveaway that this is merely someone's fanciful thinking.  It's the southern polar region.  When dunes begin to thaw there is a corresponding darkening of the soil which can look like bushes, trees (as seen from above), etc.

As for the "lakes"?  Very likely are expanses of sand.

Re: Has anyone else seen these lakes?

There are a few spots on Mars (deep in the Hellas Basin is one of them) where the temperature and pressure are high enough for liquid water to exist at the surface. In Mars dry air, this water would quickly evaporate. A large lake might last awhile. At night it would freeze, and it would probably stay frozen most of the year.

Re: Has anyone else seen these lakes?

We still have to wait for further details from Mars.
It is a slow process, there could be frozen liquid water on Mars.
They could be an illusion of the sand surface.
Or as recent information has shown there was or still is vast quantities of flowing sulfuric acid lakes.
Untill further studies are made we will just have to speculate.

Re: Has anyone else seen these lakes?

I noticed something odd about the second picture. If we look at the area in the second picture that looks like a lake we see that there is an area of it that seems to be sunken down from the rest of the “Lake”. Clearly, this wouldn’t happen in liquid water, as water would be more or less flat. I think it is even odd for sand as you would think the winds would also blow the sand around until it is more level.

Re: Has anyone else seen these lakes?

Wow....those are NOT lakes. All you have to do is look carefully at the shading to see that they are just depressions.....and as for 'trees'...I don't think I can even start. You realize how huge these features actually are?
