This is a GGG ping, for "Astronomy and Catastrophism". The graphic in comment #1 is a bit of trick I've played. It comes from a paper published in 1991 (however, it was first published in KRONOS in 1985), "The Scars of Mars", by Donald W. Patten. The website on which it appears is a little creepy, but Patten's general idea is the same as seen in this new paper -- that a single, large impactor reached its Roche point during terminal descent, shattered, and smashed into the planet, forming a number of craters. This new paper puts the number at five, Patten attributes the formation of the "Hemisphere of Craters" to this single event, with the remaining craters having formed more or less uniformly over a much longer span of time.

Please FREEPMAIL me if you want on, off, or alter the "Gods, Graves, Glyphs" PING list --

"The point is that the ice is very recent: it appears to still be there, covered beneath a layer of dust and ash," John Murray of Britain's Open University said in a telephone interview.

The Scars of Mars
by Donald W. Patten
January 1991

It is to be noted that all 15 of the largest craters of Mars are in the Hemisphere of Craters. It is also noteworthy that the massive lava outflows of Argyre, Hellas, and Isidis undoubtedly have spread and occluded a certain significant number of craters Thus our figure of 3068 craters 20 miles and larger in diameter has been masked by these lava outflows; the original figure was even larger before lava flow and before larger craters occluded some smaller ones.

If there is a shift from our Table III, therefore, it will probably be in the direction of an even greater extreme. And the 7 percent crater count in the Opposite Hemisphere may in fact be somewhat larger than the original impact situation.

I don't know why, but the first thing that comes to mind is the Dr. Who 4-parter, Pyramids of Mars.

Zoom in on Mars:
New Highly Detailed Images
by Robert Roy Britt
15 October 2002

A new image from the Mars Global Surveyor (MGS) Mars Orbiter Camera (MOC) reveal the ridges to be part of a larger circular structure that's about 53 miles (86 kilometers) across. "It is possible that this pattern reflects an origin related to an ancient, eroded meteor impact crater that was filled-in, buried, then partially exhumed," according to scientists at Malin Space Science Systems, which operates the camera for NASA. "In this case, the ridges might be the remains of filled-in fractures in the bedrock into which the crater formed, or filled-in cracks within the material that filled the crater. Or both explanations could be wrong."

Ghosts of Impacts Past:
Ancient Hidden Craters on Mars Revealed
by Robert Roy Britt
05 November 2002

Images obtained by SPACE.com reveal hints of circular outlines and subtle depressions that appear to be craters created during tremendous asteroid or comet impacts that pummeled the Red Planet’s original crust 4 billion years ago or more. The features have since been mostly buried or eroded away... If the entombed craters exist as suspected, then the current visible surface of Mars does not represent the original crust, as some scientists have thought... Mars, Earth and the other planets are thought to have formed about 4.5 or 4.6 billion years ago. A period of heavy bombardment likely ensued, as countless rocks were cleared from the fledgling solar system. A record of the bombardment remains on the Moon, where little erosion or geologic activity takes place... "Erin's results show that the assumption many people have made that the oldest visible surface units go back to 4.6 billion years ago is wrong," the father told SPACE.com. "That means the absolute time scales people have tried to use are probably wrong. It also means there is a recoverable history on Mars that we cannot easily see, except in terms of the crater record. The surface we see is not the original crust of Mars, but something younger."
