Meteorites in the United States
Finds & Falls
According to the data base of the Meteoritical Society, 1671 verified meteorites have been found in the United States (finds + falls as of April, 2013). Below is a map depicting how many are from each state.
Many of the meteorites were found as multiple stones, sometimes years apart. The total number of individual stones is not known but is probably several times the number of meteorites. (By convention, if a meteoroid breaks apart in the atmosphere or when it hits the earth, all the fragments are considered a single meteorite with one name.)
The earliest find is Havana, an iron meteorite that was found by native Americans in prehistoric times and made into beads. The beads were later found in the Dickson Mounds archaeological site near Havana, Illinois, in the 1940's.
Bottom line: Only 1671 meteorites have been found and verified in the U.S. in the past 206 years. That's 7.6 per year.
There have been 154 observed and recovered meteorite falls in the U.S. in the past 206 years. The first was Weston (Connecticut) in 1807.
Note that although there were fewer people and the country was less settled during the first 100 years, the number of falls from 1807 through 1906 (52) is not much less than the number of falls in the last 100 years, between 1913 and 2012 (89).
The histogram below shows the
distribution of meteorite masses for the 1663 U.S. meteorites for which the
mass is known. Masses range from 0.5 grams (0.02 oz) for Cuddeback Dry Lake 006 (H6) to ~30 metric tons for
the many pieces of the Canyon
Diablo iron. At 15.5 metric tons (34,000 lbs.), Willamette
(an iron) is the largest single "stone."
