What is the Columbia Plateau known for?

The Columbia Plateau, also known as the Columbia Basin, is the site of one of the largest outpourings of lava that the world has ever seen The Columbia Plateau flood basalts are a notable example of a “Large Igneous Province,” where vast volumes of basalt are erupted over a relatively short period of time

Why is the Columbia River Plateau so flat?

The basalt was so voluminous and fluid that it completely filled the preexisting topography, forming a broad, flat plain that tilts downward to the west Geologists believe that some of these lava flows were 30 meters (100 feet) high, and flowed at speeds of up to 5 kilometers (3 miles) per hour
