A canyon, although it is unlikely for this to happen.
The city is located on the Alleghenny Plateau where the confluence of the Alleghenny River and the Mongongahela River form the Ohio River
The Colorado River cut through layers of rock over millions of years to form the Grand Canyon. The process of erosion and the uplifting of the Colorado Plateau contributed to the formation of this iconic natural wonder.

plateau
A plateau may show the effects of tectonic processes through its formation, where uplift and compression of the Earth's crust result in the creation of the plateau. Erosion can also be observed on the plateau in the form of river valleys, canyons, and sediment deposits, showcasing the impact of weathering and transportation of material over time. Together, these processes shape the plateau's landscape and reveal the dynamic interaction between tectonics and erosion.
plateaus or plateaux
Plateaux is already plural. Plateau is the singular form
a plateau probably formed when the surrounding land was eroded
Since there are approximately 6,800 different languages currently being spoken in our world, there isn't just one foreign form of the word plateau. You have to specify a language.
Lava that cuts across rock layers hardens to form a disk.
Interlocking spurs form in a river valley as a result of the meandering nature of the river's flow. When a river cuts through a landscape, it erodes the softer rock and soil, creating bends and curves. The harder rock formations on either side of the river remain, leading to the development of interlocking spurs that protrude into the valley. This pattern creates a series of alternating ridges that interlock with one another, resembling the teeth of a zipper.
