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 North Dakota?
11 meteorites from North Dakota are officially recognized in the scientific record — 1 witnessed falls and 10 finds.
What's the biggest meteorite ever found in North Dakota?
Richardton, a H5 (ordinary chondrite (high iron)) weighing 90 kg, which fell in 1918.
Can I hunt for meteorites in North Dakota?
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.
