This is a pretty nice little crater. I wonder if Oppy will wander into it. This comment reminds me very much of an exchange between Dave Scott, on the Moon, and Joe Allen, the CapCom back in Houston. It occurred just a few minutes after Scott and Irwin had discovered the "Genesis Rock," a piece of nearly pure plagioclase, at the rim of a small crater on the Appenine Front. Despite the excitement of the find, Allen was pressing the crew to move on to their next stop: Scott: Hey, Joe, this crater is a gold mine! Allen: And there might be diamonds in the next one, Dave. So, yes -- Emma Dean may have some very good finds in it. But, as always, we have to remember that Victoria might have diamonds in it... -the other Doug -------------------- “The trouble ain't that there is too many fools, but that the lightning ain't distributed right.” -Mark Twain

The hershey's kisses aren't shaped exactly like our chocolate confection, the departure from spherical is very small. Physical and color differences are very subtle, but nonetheless present.
Unlike the carbon-based rovers in Apollo, the silicon-based rovers in MER are not on a tight time schedule for the traverse since they will run out of oxygen at a known point in time. Although unlike the Black Knight they are not invincible, the rovers are far from loonies. We ought to keep moving on because the clock is ticking but not at the cost of science. The diamonds at Victoria will be there in a few Sols more. Science as well as photo-ops. --Bill -------------------- |

This is a bit off topic, but since this thread seems to have the attention of some of the geologizers, I hope it will be appreciated. I came across an abstract from last Spring's LPSC that I had somehow missed. RELATIVE AGES OF GEOMORPHIC FEATURES VISITED BY THE OPPORTUNITY ROVER.
This 2 page pdf should not be too large of a download for those on dialup, and it addresses several Meridiani observations that have resulted in many long-winded discussions here about things like ripples, cobbles, polygons, and mini-craters. I'd recommend this short paper to anyone interested in those topics. Anatolia is seen as a large scale version of volume-loss polygons observed on many scales. Mini-craters are viewed as either small craters or rimless pits...and more elongated sapping features are described as pit chains. I like the way this abstract condensed a huge amount of observations and interpretations into only 2 pages. There are a few more diamonds to be found in it. -------------------- ...Tom

It is almost an epiphany to read something that mirrors observations that you have had for a long time. I really need to spend more time reviewing the current literature. The previous post is in no way OT.
BTW, there is discussion about the ejecta apron and the Emma Dean roadcut in Squyres' current Mission Update at http://athena.cornell.edu/news/mubss/ . --Bill -------------------- |

And mixed in with the initial Navcam views of Victoria's stratigraphy we have a couple of partial-frame Pancam sequences of selected Emma Dean features. L257's here, with interesting compositional changes.

Yep, I noticed those too Bill... very interesting... I posted this over on another thread but I think it slipped past everyone...
And the one you pointed out... -------------------- |
