That hole has definitely been dug up. But it also doesn¹t appear to be a
foot deep. Perhaps in a 10 year old¹s imagination it is.
I just ran the numbers, and if we assume a spherical body (which I have to
do) moving at its aerodynamically-limited speed then a 48 g iron meteorite
would be moving around 70 m/s (~150 mph) when it reached the ground. I can
picture it digging itself in a bit on impact.
Like Mike, I¹m not going to proclaim this one to be the genuine article but
I¹m also not ready to dismiss it completely. I¹m curious to see how it pans
out. Would be nice to get some composition data to compare it with SA or
other meteorites.
Cheers,
MDF
