[meteorite-list] Holbrook under the microscope...

[Erik Fisler]

Nick,  
Love the photos, that's really great resolution!
I wouldn't say the average size of finds are falling.  You can ask Anne Black, 
my dad and I always come back from a trip with three or four stones in the 3-7 
gram range and every other time with a 10-12gram stone.
here's a video of one of our hunts: http://www.youtube.com/watch?v=xx98yRvqK3E

I would say it depends on the weather the week before you arrive and the weather 
while you are hunting.  Different combos can yield different finds in different 
spots. ^.^

Thanks to Ruben Garcia and everyone on the 99th Anniversary hunt for an 
enjoyable and enlightening weekend.  I've uploaded images of a number of the 
smallest finds collected by me and the ants.  Collecting
soil samples at regular intervals, washing them through standard screens, 
separating the residue with
magnets and examining what's left under the microscope may tell us something 
more about the 1912
fall.  With the notable exception of a few, the average size of finds seems to 
be falling.
