Hmm. Very interesting.
I was recently tryring out my "new" metal detector (thanks, Ruben) on our
property in southern Utah and discovered that the "lava bomb" boulders
strewn across the landscape are "hot rocks" and are slightly mag-attracted.
The boulders were ejected from Boulder Mountain and Thousand Lake Mountain
20 to 30 million years ago in a lava flow eruption. They were distributed
around the area by subsequent glacial activity. In addition, I found a great
deal of aluminum foil, and a few bullet casings. No meteorites... yet.

Subject: [meteorite-list] Volcanic Ash is Magnetic
Well...just had an Eureka moment. I was sitting here at my desk with a
bottle of volcanic ash from Mt. St. Helens and a earth magnet in my hand.
I
brought the magnet to the ash and discovered that the ash was attracted
to
it. I didn't know this before...son of a gun. :O)
