WM, Dust bowls are depressions in the soil where turkey roll around in to get dust in their feathers to discourage biting mites. They are most commonly found in dry sandy or silty soils. You should be able to identify them pretty easily. I've actually seen hens dust themselves frequently. There will be tracks in & around such bowls. If you can find a cluster of them you got money. Just set up your blind in range. This is especially a good way to hunt if you do heavily pressured public land where the toms are spooked by decoys. The bowls act as your decoys.
