Chuck, Your rain gutters collect terrestrial dust as well as some micro-meteors. However, the environment in your rain gutters are not commonly rich in dust made up of magnetite (Fe302). Run a magnet through your rain gutters and you will be surprised at how much magnetite you pick up and the majority is micro-meteors. Thanks Rodger C.

I have searched for micro-meteorites around my house in the past, sifting through rain-gutter debris, but like the aricle's author when he began his search, was always defeated by the staggering amount of "meteor-wrongs". Industruial particulates, common terrestrial dust, etc. I may take another stab at it one of these days. There's always been a lot of talk about a Salt Flats meteorite search, it should be easy to find a strewnfield if you can get out there quickly after a fall, but never heard of anyone doing anything more than a casual search, so I'm curious too! Bob, if you can make it to the next Liver & Onions luncheon, several of us will be bringing meteorite specimens for show & tell. I have a specimen of the Chelyabinsk bolide of 2013.

I’m intrigued by today’s article in the New York Times science section about amateur micro-meteorite collection. If they can find such beautiful objects in gutters and on roofs, I would imagine that the salt flats should have collected a lot of objects smaller than bowling balls. Has anyone of this list successfully searched and collected any there? Any tips to share?
