Beneath the rolling grasslands and geothermal wonders of Yellowstone National Park lies a geological structure of immense power, the Yellowstone caldera. The caldera floor, which sits at an elevation of approximately 7,500 feet above sea level, varies in depth relative to the surrounding rim.
Measuring Depths Of Yellowstone Caldera
7,500 feet Surface level within the depressed basin Maximum Caldera Depression Approx. This vast volcanic crater is often misunderstood, conjuring images of a simple crater or a bubbling cauldron.
Measuring the Depths Determining the exact depth of the Yellowstone caldera is not a matter of dropping a tape measure into a visible pit. More importantly, the current shallow magma reservoir, a pocket of partially molten rock, lies roughly 5 to 10 miles below the surface.
Measuring Depths Of Yellowstone Caldera
The deepest points of the caldera depression are found in specific basins created by subsidence. 1,000 - 1,500 feet Vertical drop from rim to floor at deepest points Shallow Magma Reservoir 5 - 10 miles deep Source of current ground swelling and geothermal activity The Role of Ancient Eruptions.
