| Similarly, the big polluted river that snakes its way like a mudflow through the coastal industrial city started out high in the distant mountains as a pristine stream. |
| Example for drainage measures to prevent slopes from sliding respectively to avoid mudflow in mountains. |
| The hot gases and magma melted the ice and snow that covered the mountain and the resulting mudflow continued throughout the night and the following day. |
| A newly formed river then flowed through the Canyon formed by the mudflow. |
| Locally, a basalt and basalt-clast mudflow occurs near the top of the formation. |
| Great destruction also can result when ash collects on a high snowfield or glacier, melting large quantities of ice into a flood that can rush down a volcano's slopes as an unstoppable mudflow. |
