In fact there may very well be some pieces that are worth hundreds of dollars per/gram... How so? I and Dr. John Wasson, in a project that I proposed, but those people at MCE refused altogther, after 10 years of jumping through their ever more impossible hoops... we had as one of our objectives collecting ALL meteorite oxides of any appreciable size. This was an added part of the project when Dr. Wasson and myself were very priviledged to have seen the original burial cyst with actual chunks of the Winona Meteorte inside. It was very well preserved, cyst extracted from the ground with perhaps 10 lbs of Winona meteortes inside! This was not on display, but tucked in a back storage room. Upon examining a piece, we were both struck by the trememdous similarity to the oxide pieces found at meteor crater. In fact, I am certain that over 25 years ago, not far from the crater I found a weird oxide chunk with the same green stains that Winona has as a major characteristic separating it from the much more common meteorite shales. Dr. Wasson expressed to me that he thinks after seeing this, and with my report of a possible similar find at meteor crater that Winona is a silicate fragment from that meteorite that created the crater. In fact, he said to me that the type of meteorite that made the crater SHOULD have silicates... and some fragments do in fact have some, as I had one that I sold to him with two peanut sized silicate inclusions in it. That Winona might be related to the meteorite that made meteor crater is a very exciting possibllity... one that needs to be explored. But now, because MCE aka Bar-T-Bar is recalcitrant in giving "official" permits to make collections, we may never know. But keep your eyes open... If you find in that pile of oxides, a strange one with dark green Ni streaks, and a somewhat lighter shade of dark tan... Better cut it, and examine it carefully... It could be the another definitive sample of the Winona Meteorite... tying it with meteor crater. And who, at any time ever spent the time to really examine the multitudes of oxide found around the crater? Tucked in all of that could be silicate inclusions, disguised, and ignored... Winonites! The original found by observant Native Americans 900 years ago as they were hunting game around the crater. And today such similar silicates may be overlooked and tossed aside by all those collectors focused only on solid iron meteortes! What a find in the midst of that oxide such would be! A true statement of discovery for the records! Steve Schoner http://www.geocites.com/meteorite_identification __________________________________ Do you Yahoo!? The New Yahoo! Search - Faster. Easier.
