The Tangipahoa River near Amite City draws agate, carnelian, and jasper from the same Citronelle gravel belt that feeds the Amite, and its LA 16 crossing is a long-known access point for collectors. Rounded pebbles under two inches wash onto the bars, best searched at low water when the gravel is exposed. It is a dependable Florida Parishes alternative when the Amite runs high. Reported finds include agate. Below: coordinates, access notes, nearby spots, and trip-planning links.
