The Enormous Waterfall That Once Surpassed Niagara Falls

Chapter 1: The Marvel of Dry Falls
The world knows Niagara Falls for its remarkable size and the massive flow of water that cascades over it daily. This iconic destination ranks among North America's most frequented tourist spots. However, tucked away from the usual tourist paths lies a geological wonder that narrates a stunning story of Earth's past.
Situated in Central Washington, Dry Falls is an impressive cliff that overlooks a small lake. At first glance, these cliffs might not seem extraordinary, as similar formations can be found throughout the American West. Yet, through a geologist's lens, Dry Falls reveals a captivating history. Once, it was a waterfall comparable to Niagara Falls but on a far grander scale.
The unique shape of Niagara Falls is attributed to the flow of water. Typically, water flows more swiftly in the center of a river than along the edges. This differential flow leads to quicker erosion in the middle, forming a characteristic horseshoe shape. A similar, albeit larger, process occurred at Dry Falls.
Standing before Dry Falls invites a glimpse into a distant era marked by significant geological upheaval.
Section 1.1: The Dimensions of Dry Falls
When this colossal waterfall was active, it stretched five times the width of Niagara Falls, which measures about 3,000 feet across. In contrast, Dry Falls spans an astonishing 3.5 miles. At the foot of the cliffs, ancient plunge pools reveal where torrents of water once crashed down, creating deep impressions in the earth. Observing these dry basins today makes it challenging to imagine the immense forces at play.
These plunge pools lie 400 feet below the cliff's edge. Although Dry Falls is not the tallest waterfall globally, its height—over twice that of Niagara Falls—is still impressive. The sound of water thundering over these cliffs must have been overwhelming.
The water cascading over Dry Falls is estimated to have reached speeds of 65 miles per hour, significantly faster than the average flow of the Niagara River, which typically moves at just 5 miles per hour. The upper cascades of Niagara Falls can attain speeds of up to 40 miles per hour, but the flow that shaped Dry Falls was unparalleled, surpassing the combined flow of all major rivers worldwide.

Section 1.2: The Source of the Water
What caused such an immense volume of water to create Dry Falls, and where did it all go?
At the end of the last Glacial Period, massive ice sheets were moving across North America. As these glaciers melted, they released millions of gallons of water, forming numerous lakes, including the gigantic Lake Missoula.
Simultaneously, ice damming occurred when frozen water obstructed natural flow paths. As water levels rose behind these dams, the pressure eventually broke them, unleashing torrents across the landscape. This cycle resulted in vast volumes of water surging out of Montana, ultimately leading to the formation of Dry Falls.
As the water from Lake Missoula rushed out, it carved significant channels and directly contributed to the creation of Dry Falls. The sheer volume of water that once cascaded over these cliffs was nothing short of extraordinary.
Chapter 2: The Fate of the Water
Dry Falls would be even more astounding if it still flowed with water. So, what happened to it?
As the glaciers melted and retreated, the landscape stabilized. The Columbia River, the major watercourse in the area, returned to its banks and began to flow more predictably. Without the glaciers' influence and the additional water from melting ice, the river's course shifted away from Dry Falls, leaving it dry.
