One of the final stops on our Chilean voyage was Jarellon. Located on the Chile/Bolivia border near the La Pacana Caldera, Jarellon is the surface expression of a large ring dike, estimated at less than 5.6 million years old. Notable about the ring dike is the extremely abundant obsidian clasts that are weathering out. Red, black, and snowflake obsidian can be found, much to our delight.
