Pollen in dirt tells more stories than I thought

I just read an article about how archaeologists study old pollen. They take soil samples from dig sites and look at the pollen grains. This helps them figure out what plants grew there long ago. For example, in one site, they found pollen from crops that show early farming. In my experience, details like this can paint a big picture. Your mileage may vary, but I find it fascinating how small things reveal history. Take this with a grain of salt, but it's a skill I'd love to learn more about.

How deep do they usually dig to get those soil samples? I always thought pollen was just a sneeze thing, but it's wild they can tell apart wind-pollinated crops from insect-pollinated plants in old dirt. Basically changed my whole view from "ugh, pollen" to seeing it as tiny time capsules.

Remember that time they found corn pollen in a bog near my town? They went down about three feet and hit a layer full of it, right below some tree pollen. That told us exactly when farming started there, way before any written records. It's crazy how a bit of old mud can rewrite what we know about a place.

@maryhunt, they often dig a few feet down to avoid modern contamination in the soil. I've used a hand auger to pull up core samples from different depths at a local historical site. Matching pollen layers to time periods helps trace farming changes over time. Seeing crop pollen in a core sample really shows how people lived back then.
