Down here you can walk the fire breaks, after a fire, that the forest service ploy and find an arrow heads every now and then. I found a site where there must have been a camp because there was a lot of chip and broken or unfinished arrow heads. Found another site where the Poverty Indians had a village after a canal was dug. There was a layer of black dirt in the canal bank which was a dead give away. Found round clay ball and, more rare, conical ball which the indians would put in fires and after they got hot they would drop in leather bag of liquid to heat it. There were also lots of animal bones. In the river deltas it was easy to find camp sites because all you had to do was look for a clump of trees in the middle of the marsh. The indians created little mounds of dry land with the clam shell from all the river clams they ate. Mostly broken pottery is all I ever found there.
