This volcanic rock, forged in temperatures exceeding 700 degrees Celsius, forms the skeletal foundation of the Yellowstone Plateau. Table Mountain Basalt: Found in the Lamar Valley, this extensive layer represents the more fluid, basaltic compositions that traveled further than their rhyolitic counterparts.
Basaltic Magma Lower Viscosity Flows Greater Distance
Rhodes Flow: Located near the Tower-Roosevelt area, this flow provides a cross-section of fractured rock that illustrates the cooling process of thick lava. These solidified rivers of rock serve as durable markers of the continent’s violent past.
These cracks allow water to penetrate, initiating chemical weathering that will eventually break the rock down into soil over millennia. Understanding these flows is essential to grasping the dynamic geological engine that powers the park’s famous hydrothermal features and wide-open valleys.
Basaltic Magma Lower Viscosity Flows Greater Distance
High-silica rhyolitic magma is extremely viscous, trapping gases and leading to explosive eruptions that shatter rock into pumice and ash. The Mechanisms of Yellowstone's Volcanic Output The source of this material is not a simple, single pipe but a complex system involving a deep mantle plume and a shallow, partially molten magma chamber.
