Summary
[edit]DescriptionUpper Falls of the Yellowstone River (Yellowstone, Wyoming, USA) 26 (47602395412).jpg |
From park signage: Upper Falls of the Yellowstone River A waterfall forms in a river channel where harder rocks meet softer rocks that erode more easily and quickly. Here, volcanic and hydrothermal activity have created the 109-foot Upper Falls. Why here? 1) About 480,000 years ago, lava formed a layer of rock that resists erosion. The lava naturally cracks in a zig-zag pattern. 2) Over time, hydrothermal springs rose through some of these cracks, altering and weakening the lava. 3) The Yellowstone River flowed through the zig-zag cracks and eroded its river channel. Once the river reached the softer, hydrothermally-altered rock, erosion increased and created the Upper Falls. |
