Meteorites Found in Oregon: 6 Documented
Oregon has 6 officially recognized meteorites — 1 witnessed fall and 5 finds. The largest, Willamette (Iron, IIIAB — iron meteorite — nickel-iron metal), weighed 15.5 tonnes. The record here spans 105 years — from Sam's Valley in 1894 to Morrow County in 1999. Famous names include Willamette.

Famous Oregon meteorites
The largest meteorite ever found in the US — a 15.5-ton iron discovered in Oregon in 1902, now the centerpiece of the American Museum of Natural History. No impact crater was ever found; glaciers likely rafted it from Canada.

Reading the classifications
The most common meteorites — stony, with visible metal flecks. H = high iron content, L = low, LL = very low. The digit (3–6) says how much the parent asteroid heated it: 3 is the most pristine.
Primitive, carbon-bearing stones that predate the planets — some carry water-bearing minerals and amino acids. Fragile and rare on the ground.
Solid nickel-iron from the shattered cores of asteroids. Dense, magnetic, and the easiest meteorites to recognize — most of the biggest US finds are irons.
The showpieces: pallasites are gem-quality olivine suspended in polished metal, from the core-mantle boundary of destroyed asteroids.
Volcanic rocks from bodies large enough to melt — most trace to the asteroid Vesta; the rarest are from the Moon and Mars.
Frequently Asked Questions
How many meteorites have been found in Oregon?
6 meteorites from Oregon are officially recognized in the scientific record — 1 witnessed falls and 5 finds.
What's the biggest meteorite ever found in Oregon?
Willamette, a Iron, IIIAB (iron meteorite — nickel-iron metal) weighing 15.5 tonnes, found in 1902.
Can I hunt for meteorites in Oregon?
On BLM-managed public land, casual collecting is legal without a permit: surface finds, up to 10 lb per person per year, personal use only. National parks prohibit all collecting, and on private land the meteorite belongs to the landowner. Always verify land status before hunting.
How do I know if a rock is a meteorite?
Quick field checks: meteorites are unusually dense, most attract a magnet (iron-nickel content), fresh ones have a thin black fusion crust, and many show regmaglypts (thumbprint-like depressions). Slag and magnetite are the common false alarms — our 60-second field test walks through all of it.
