Reading the classifications

H, L, LL (ordinary chondrites)

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.

Carbonaceous chondrites (CM, CV, CO…)

Primitive, carbon-bearing stones that predate the planets — some carry water-bearing minerals and amino acids. Fragile and rare on the ground.

Irons (IAB, IIIAB…)

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.

Pallasites & mesosiderites (stony-irons)

The showpieces: pallasites are gem-quality olivine suspended in polished metal, from the core-mantle boundary of destroyed asteroids.

Achondrites (eucrite, howardite…)

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 Minnesota?

10 meteorites from Minnesota are officially recognized in the scientific record — 1 witnessed falls and 9 finds.

What's the biggest meteorite ever found in Minnesota?

Turtle River, a Iron, IIIAB (iron meteorite — nickel-iron metal) weighing 22.4 kg, found in 1953.

Can I hunt for meteorites in Minnesota?

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.
