E.P., list,

out of curiousity: as you were previously talking about radio carbon dating, do you pull that "17 February" from the data provided by Cassidy et al (1972, 1996)?

Their radio carbon dating of charcoal fragments extracted from the bottom of one of the craters gave an age of "~ 4,000 B.P." - one tends to interpret this figure rather as an approximation ...

Hi - 
The correct date for Campo de Cielo appears to be 17 February, 2,325 BCE. 
25 October, 2,360 BCE is for the Rio Cuarto Impacts, which also occurred at 
"Matawil".
My apology for the error.
