Last day in Mexico

We have reached our last day here in Mexico. I'm sad to have to leave so soon. I have learned so much about the history and culture of Purrto Penasco and the Sea of Cortez. The people of CEDO have been so kind and willing to teach us about anything and everything that we want to know about the Ocean. We went to a trona salt mine. Trona is mined primarily for sodium carbonate. Trona also is a common source of soda ash that is used to manufacturer glass, chemicals and detergents. Jason
