ALABAMA
TRIP: This was the first GMS trip to a private gravel location. Though there was some collecting, this was primarily a geological education trip. A company geologist told us about the fascinating geology of the area and answered questions about the geology as well as the uses of the gravel.
COLLECTING: Gravel included jasper, agate, oolitic material, and petrified wood. Jaspers were mostly black, brown, and some pink. The agate had fortifications, but did not have much color. Most of the oolitic material had good contrast between ooids and matrix. The petrified wood ranged from gravel size up to one foot or so.
