ravines
Narrow eroded valleys
Ravines are deep, narrow valleys or gorges, typically carved by running water over time.
They have steep sides and are smaller than canyons but larger than gullies.
The word often suggests wild or difficult terrain: The hikers had to cross several ravines before reaching camp.
Streams frequently run along ravine floors.
