After months of rock collecting along my beach in Ozaukee County, Wisconsin, I have developed a somewhat discerning eye. At first, I picked up any old hunk of limestone containing fossilized impressions in attempts to figure out which creatures populated the Devonian seabed that is now this region’s bedrock. Now I scan for, among other things, unusual shapes among the consistently rounded lake stones.

This cracked stone jumped out at me on a flashlight-lit night walk along the beach with my German Shepherd. I figured it was a meteorite immediately because of the rock’s pronounced cone and shattered state. This fist-sized stone looks like a Martian chondrite to my eye.

Meteorites consist of material that formed in the cloud of dust and gas from which the solar system formed. Stony meteorites like this one are called chondrites. These meteorites contain small amounts of fine-grained iron-nickel metal.
