Found a weird trick for spotting surface finds in plowed fields | Archaeology Discoveries

I was walking a site in eastern Colorado last fall, scanning for lithics, and kept missing stuff in the furrows. Instead of just looking down, I started walking with the sun behind me, using the long morning shadows to highlight shapes. It doubled my finds in an hour. Anyone have other low-tech field survey tricks that actually work?

Try walking sideways along the furrows, it looks ridiculous but helps you scan both sides. My only other trick is just accepting I'll miss half the stuff anyway.

Heard a guy talk about using a cheap plastic spray bottle filled with water. He'd give a light mist over a patch of dirt, said it darkens the soil just enough to make lighter colored chert or quartzite flakes pop right out. Tried it myself on a dry day and it actually worked on some small debitage I'd walked past twice. Doesn't help much with darker materials, but for pale stone it's a game changer. Just plain water, nothing fancy.
