Dogs may be naturally sensitive to the burnt odor of recent fusion crusts on meteorites. A fusion crust is often shiny black, like black patent-leather shoes. Or a fresh fracture of obsidian.
Meteorites do not always embed themselves in the ground, even they may be travelling at supersonic speeds a few miles before. Air becomes more dense with increased water vapor the closer to sea level you get. The Washougal, Washington meteorite from the 2 July 1939 was estimated to be travelling at 160,000 mph just seconds before impact. Just imagine the sonic boom: a term which had not yet been invented at the time! Yet only one piece that was found was pumice-light and found resting on top of a bed of leaf litter. There was no impact crater. This also proves that not all meteorites are heavy nor metallic.
Ironically, the people who heard the Washougal, Washington meteorite and tracked it in the air were convinced, in some cases, that it was travelling 180 degrees from where it came from. Auditory illusion. Once the speed of a meteorite goes under supersonic speed, the sound wave produced before-hand continues onward, sometimes preceding an actual impact.
That's why it is so important to get as many first-hand accounts of meteor sightings before impact, in order to approximate where an impact actually occurred.
Weird? You betcha! Counter-intuitive? Big time! But finding pieces of a meteorite, then back-tracking who saw what where, and when, are often weird and counter-intuitive.
But consider, too, that the Willamette Meteorite, which was found in 1903 about 15 miles from where I live, did not fall there. It is suspected of being deposited thousands of years ago in an iceberg after the ice dam on Lake Missoula broke. Since Lake Missoula broke between 30 and 150 times during the last Ice Age, it is not known where the original impact site is: British Columbia, Idaho, and Montana are all possibilities.
All this proves, of course, is that meteorites, like gold, are where you find them.
