The Case of the Mysterious Clay Particles

Two Reports, Miles Apart

In July, M.D. (Hall County) and K.E. (Marietta) reported identical phenomena: tiny, biscuit-shaped red-clay pellets appearing on decks, driveways, and vehicles—mostly in open areas, not under trees. Pellets crumbled to fine red dust.

On-Site Investigation

An Extension volunteer visited the Marietta site. No ant mounds, mud-dauber nests, or insects were visible. Pellets were confirmed as aggregated red clay, ~2× BB size.

Expert Theories

• Ground-nesting yellowjackets excavating?
• Potter wasps/dirt daubers dropping balls?
• Caterpillar droppings?
• Artillery fungus?
• Construction dust or blasting?

Conclusion: Very small dirt clods. Source: Unknown. Cue Twilight Zone theme.
