During a volcanic eruption in the early 1900’s, this area of Santiago was covered with flowing lava. Today, the hardened fields of black rock create a geologic wonderland. We will take advantage of the cool of early morning for awalk to view strange twisting hardened lava flows, collapse craters, and everyone’s favorite, the hornitos orlava ovens. Tall red scoria cones and pioneer plants also dot this unusual and very young landscape.
