The local culture, the tongva,were very skilled craftsmen, I've seen some examples of there work. Due to the lack of clay deposits, they adapted and used what was available. They carved bowls and pots out of basalt and weaved baskets out of the local reeds, which were capable of holding water. They also traveled between the mainland and the channel islands on reed boats, so they did get around. If the bead is artifact, its probably not from around here. Is there anyway to connect it with which culture did make it. Also, if anyne knows, what time period were clay beads like this produced?
