Re: [meteorite-list] Article : 21st Century Meteorite Falls, Part Two

2016-10-20 Thread Galactic Stone & Ironworks via Meteorite-list
Hi Carl and List,

I am just guessing about Morocco. It seems like Tissint really
hammered home the notion of chasing meteorite falls there.

We have seen a total of 4 witnessed falls in California since 2000 :

Red Canyon Lake (2007)
Sutter's Mill (2012)
Novato (2012)
Creston (2015)

The only other California fall in the Met Bull is San Juan Capistrano,
which was way back in 1973.

Four out of five California falls happened in the last 10 years.

I agree about lunar falls - we are long overdue. I wonder if one of
those fireballs that was chased without a recovery was actually a
lunar fall - maybe the hunters walked right over it and didn't
realize. (Unlikely now I think). I always wonder how many lunar
meteorites are laying around the USA and are overlooked because they
don't look like typical meteorites and they are metal-poor. There has
to some out there somewhere.  We haven't had a single lunar find
anywhere in the USA (yet).

There has only been 1 winonaite fall : Pontlyfni (UK, 1931)

There have been zero CH falls.

There might be others, but I can't think of them right offhand.

Best regards,

MikeG

I find the relatively static number of falls very surprising, considering

2016-10-20 Thread Carl Agee via Meteorite-list
Always an interesting topic!

A couple of things come to mind:

Morocco has 8 falls in the 21st century, which you suggest has to do
with the meteorite-savvy population and desert terrain. California has
a very similar area and population density -- also a west facing coast
line, a fair amount of desert, and a mountain range. How many 21st
century falls in CA?

We are over-due for a lunar falls! There are now 265 classified lunars
-- all of them finds. Compare that with 5 martian falls and 177
classified finds, or for example mesosiderites with 6 falls and 261
classified finds. Aubrites have 9 falls and 63 finds.

Brachinites have no falls (40 finds), any others?
