A cartoon showing the most basic (yet generally effective) ways to tell a meteorite from a terrestrial rock. The easiest places to search for meteorites are places that don’t have a lot of stuff in the way to obscure your view. Deserts, particularly deserts with naturally light-colored rocks, and ice fields are good areas to recognize meteorites.

For instance, if you happen to be strolling around the desert and want to look for meteorites during your hike, just walk around with a magnet on a stick. You will likely see many dark rocks, so this “magnet-on-a-stick” method is the easiest way to eliminate nonmagnetic things that are probably not meteorites without bending over hundreds of times. In fact, this is such a famous method, you may even be familiar with the old meteorite prospector’s saying: “If your stick doesn’t stick, you must not a-quit… looking.”

Whereas the magnetic method is probably the best choice when there are a lot of dark rocks around, there are vast areas of the planet that have a noticeable lack of dark objects, making the “hey-that-is-a-dark-rock” method a surprisingly useful meteorite location tool. In fact, the most productive meteorite hunting grounds on Earth are areas that (1) naturally lack dark rocks and (2) are devoid of vision-obscuring vegetation. This magic combination makes it far easier to locate meteorites that have fallen over the years. In case you are looking for an adventurous vacation that may help advance science in the process, here is a compiled list of the most important meteorite hunting grounds below.
