Those dunes on both sides of the described shoreline, are meters tall and wide, steep, and incessant across much of the crater floor. 'Sand bogs'. With our current best shot-put technique of landing ellipse attempts at landing co-ordinates we'll be lucky to miss the main dune areas, and strike a spot a great distance from the shoreline. We have a 'mile to walk' to strike a terrain target that small, and only with later equipment designs. There are many HiRISE photos which seem to show ponding and lake type margins, but most persons still hang their hats on the 'insufficient air pressure' as a standard reason for denying that these could be younger than two billions years. For my Earth trained eyes they appear much younger than that as probable water bearing lakes and ponds. The area has very serious hazards for a lander, or even a mobile rover, to cope with.

The sun was colder long ago than it is now. Still the climate seems to have been warmer om mars several hundred million years ago, and also on earth. Perhaps Mars and Earth at that time had some other warming process, for example interior heating. Or perhaps there were more greehouse gasses in the ethmosphere at former times.

Must i say more? I MAKE MY POINT!..,i hope.. its really cool to actually find a dried (LAKE!) on Mars i mean common thats alot of proof that there was life on Mars,hence maybe there is NOW under Mars crust there could be still living there!!!!
Must i say more?
I MAKE MY POINT!..,i hope..

Specifically, what would cause such actions as describe in the posted comments? Would really like to here more from Cecil as it relates to the comments left.

It's what remains of a dried up lake on the surface of Mars, yet another fantastic image brought to us by the cameras on the High Resolution Imaging Science Experiment (HiRISE.) This is a closeup of the largest of the "fans" leftover from the lake in the bottom of Holden Crater, an 87-mile (140-kilometer) wide crater in the bottom of the larger Holden Basin on Mars. What's interesting about a dried up lake bed, besides the spectacular image? Well, it's the perfect place to start a search for life on Mars. A nice, calm lake would be a likely place for life to form. This site is one of the six possible landing sites for the NASA's Mars Science Laboratory, which launches next year and will try to answer the question of whether life on Mars existed at one time, or continues to thrive there.

VERY IMPORTANT TO GET SAMPLES OF THE WHITE SEDIMENT NEAR THE UNMISTAKEABLE SHORE. THESE MAY HAVE BEEN FORMED BY SUPERHEATING AND THE QUICK RETREAT OF THE FLUID SEA. MAY RENDER WHAT WENT IN THE ATMOSPHERE TO TOXIFY THE ENVIRONMENT AND ESCENTS OF THE FORMER ATMOSPHERE.
