What were the main events that happened after the Valles Caldera collapsed?
A bowl formed, making it impossible for precipitation to escape, and thus the first of many “caldera lakes” was created. An example of this phenomenon can be seen at Crater Lake in Oregon (which is a caldera), and also at Yellowstone Lake in Yellowstone National Park (the lake being part of the larger caldera in Yellowstone, which is 40 miles wide, compared to the 12-mile-wide Valles Caldera). Subsequently, the caldera floor began to rise as magma pushed towards the surface again. Without penetrating the surface, the magma managed to bulge the center of the caldera up to a height of more than 3,000 feet above the floor. This “resurgent dome” is now known as Redondo Peak (elev. 11,254). Next, ring fracture domes were formed by the area along the caldera “ring fracture” through “toothpaste model” eruptions (gradual, relatively non-violent eruptions) . The ring fracture is the roughly circular ring along which the earth collapsed and formed the Valles Caldera. The caldera ring fracture do
