Lisa Morgan is a scientist emeritus, and former senior research geologist, for the U.S. Geological Survey. Her focus is on the geology and geophysics of volcanic terrains. She has studied the Yellowstone hot spot and Yellowstone Lake for more than 20 years.
Northern and western Yellowstone Lake is within the Yellowstone Caldera, sometimes dubbed Yellowstone’s supervolcano, and covers the magma chamber deep beneath the surface. This results in extremely active lake-bottom hydrothermal areas with very high heat flow values, multiple large (more than 330 feet in diameter) hydrothermal explosion craters, dozens of hydrothermal domes and hundreds of active […]
