The Eruption - At this famous overlook of Valle Grande we have crossed the rim and dropped down into the magnificent Valles Caldera. Across the valley to the NW is Redondo, the caldera's resurgent dome. Here we will discuss the model for the Valles eruption presented by 3 geologists (Smith, Bailey, and Ross), along with their publication of a geologic map for the Jemez Mountains. Their groundbreaking research made the Valles Caldera world famous - at least in the world of volcanology! We also discuss the dynamic geology inside the caldera since caldera formation, including 8 significant volcanoes. A Google Earth flight will show how topography around the caldera dictated the distribution of pyroclastic flows.
