<P>Steve, thanks. Have you looked at meteor crater on terra- server.com? It is so cool you can zoom right down to the crater! I found it interesting that you could see an area from the craters north rim that is lighter color than the rest of the desert! It looks a little like the moon.<BR>Thanks, Tom</P></DIV>

<DIV></DIV>
<DIV></DIV>It has been 6 or more years since I have been out
<DIV></DIV>there.
<DIV></DIV>
<DIV></DIV>But as I recall, I remember finding a shard of
<DIV></DIV>Coconino sandstone about 5 miles due west of the
<DIV></DIV>crater on what was Kiabab limestone. Whether it was
<DIV></DIV>transported there or blown there by the impact I
<DIV></DIV>cannot say.
<DIV></DIV>
<DIV></DIV>However, I also found a number of .5 to 20 gram or so
<DIV></DIV>irons that were definitely the shrapnel variety. Now
<DIV></DIV>this surprised me as I was not expecting such small
<DIV></DIV>pieces to be found 5 plus miles from the crater
<DIV></DIV>proper. And more surprising, perhpas, was the fact
<DIV></DIV>that nothing larger than 470 grams was found in the
<DIV></DIV>several square miles that I searched. This was
<DIV></DIV>consistent with the map that Holsinger had made in
<DIV></DIV>1909--- no larger irons greater than 1 lb were found
<DIV></DIV>there. But the small pieces I found interesting, as
<DIV></DIV>did Roddy and Shoemaker. It was their opinion that
<DIV></DIV>these were indeed "shrapnel" and that a "ray" of
<DIV></DIV>material must have extended in the westerly direction
<DIV></DIV>extending due west and southwest of the crater.
<DIV></DIV>
<DIV></DIV>This is also confirmed with regards to reports of
<DIV></DIV>numerous small irons having been found 1.5 to 3.5
<DIV></DIV>miles due west and southwest of the crater.
<DIV></DIV>
<DIV></DIV>As per the agreement that I was bound to (I think I
<DIV></DIV>might go into the details of this later just to show
<DIV></DIV>the nonsense and stonewalling that I had to go
<DIV></DIV>through) all material that I collected was to be sent
<DIV></DIV>to UCLA and or ASU, which I did. But due to the
<DIV></DIV>aforementioned stonewalling the main objectives of the
<DIV></DIV>project remain unfulfilled.
<DIV></DIV>
<DIV></DIV>And now I am too old, and arthritic to complete it
<DIV></DIV>even if I were allowed to.
<DIV></DIV>
<DIV></DIV>And all the while irons still are being dug up, not
<DIV></DIV>documented, and eventually not enough will remain to
<DIV></DIV>make any future collection as I had envisioned over 20
<DIV></DIV>years ago meaningful.
<DIV></DIV>
<DIV></DIV>Winona, silicate and graphite inclusion questions, the
<DIV></DIV>Type I, II, and III iron relationships.. and other
<DIV></DIV>potential questions will not be answered.

<P>Hello List, I wrote this to steve in a reply to his
<DIV></DIV>email, but it did not make it to the List: )I don't
<DIV></DIV>know if it made it to him either. Any one can answer
<DIV></DIV>if they know.
<P></P>
<DIV></DIV>
<P>Hello Steven, you sound like the perfect person to
<DIV></DIV>ask this question too! Does any one know how far away
<DIV></DIV>from the center of the crater can material that once
<DIV></DIV>was in the crater be found? In other words (i can't
<DIV></DIV>understand the question myself) How far away from the
<DIV></DIV>crater can you find rocks that where part of the
<DIV></DIV>ground before the meteor hit? <BR><BR>Thanks, Tom
