[meteorite-list] Franconia AREA (was, Re: ...terminology...)

Tue Apr 30 08:47:26 EDT 2013

Michael, Bob, Anne, Jim, Erik, List,

Though it appears that the trend line is the same for all the different 
meteorites, with the smallest stones at the n.w. and getting larger to 
the s.e., there's at least one reason why this may not be entirely true 
for all the different falls. It's possible the sampling is not 
geographically big enough, width wise. Due to the n.w. to s.e. lay of 
the biggest fall, that's where the focus was. Everyone seems to search 
where others are finding rocks and it's hard to stray too far off that 
tack, if one gets too far off to the side and doesn't find something 
they tend to meander back to more 'likely' ground, keeping the hunt 
area narrow and moving in the general direction of the field. One of 
the other, smaller falls like the L chondrites may in fact bisect the 
Buck Mountain or Franconia strerwn field, cutting crosswise, east to 
west, but if nobody goes far enough out to the sides it could be 
overlooked. My real life, possible example of this scenario; Scott and 
Terri Johnson pull up onto the scene for the first time, don't know 
exactly where to hunt, Bob tells them where to park, and BAM, they find 
a seven pounder! It was 1/2 mile off to the side from the next closest 
find and from the outer edge of the main trend area, and I know of no 
other meteorites found in the immediate vicinity. This stone is likely 
paired to one of the known's but which one? Does it hint at another 
trend line?

I think I'll spend some more time out on the sides, looking to the west 
toward the other DCA.

Sincerely,
Larry Atkins

And even if there was, I think the chances of a glacier arranging who
knows how many separate meteorite falls into a typical strewn field
ellipse distribution may be even less than the chances of so many
falls concentrated in one area along the same trend line.  After I win
the lottery I'll fund the effort to figure it out, because I think my
chances at the lotto are better than multiple falls happening in the
exact same strewn field ellipse over the millennia.

Michael in so. Cal.
