Greenland’s Subglacial Surprises: How Subglacial Breakouts Might Have Shaped Ice Age Landscapes
Recent discoveries in Greenland are reshaping our understanding of massive flood events beneath ice sheets, offering compelling new perspectives on the formation of some Ice Age Floods-related features. Two recent studies highlight an unprecedented sub-glacial flood in 2014, where a staggering 90 billion liters of meltwater unexpectedly burst through nearly 91 meters (300 feet) of solid ice. This previously undocumented phenomenon in Greenland involved a massive volume of water punching upwards, fracturing the surface, and creating a 2-square-kilometer (0.77 square-mile) crater 85 meters (279 feet) deep. Satellite data revealed that the ice surface dropped dramatically after having bulged from water pressure. Evidence downstream showed a heavily fractured area with large ice boulders and a scoured ice surface, indicative of immense erosive power. This event challenges previous assumptions that the base of ice sheets is always frozen solid and provides critical insights into the destructive potential of sub-glacial meltwater. While the iconic Missoula Floods are well-established as a result of glacial lake outbursts, this Greenland discovery suggests that other, perhaps more localized or intermittent, sub-glacial flood breakouts could have played a significant role in shaping the landscape during past ice ages. Such events could explain certain geomorphological features that don’t neatly fit the Missoula Flood narrative, such as Moses Coulee and possibly much of the Upper Grand Coulee, opening new avenues for research into the diverse origins of Ice Age Floods-related landforms.

Moses Coulee: An Ice Age Enigma
Washington state is famous for its dramatic landscapes, many carved by the immense power of the Ice Age Floods. We know the stories of the Grand Coulee, Palouse Canyon, and the Potholes. But tucked away in north-central Washington, cutting a path from northeast to southwest across the Okanagan Plateau, lies Moses Coulee – perhaps the most mysterious of them all. Unlike its famous cousins, Moses Coulee doesn’t quite fit the standard narrative. Its head seemingly emerges from beneath the Wisconsin Withrow Moraine, and its very formation presents a fascinating puzzle for geologists. Flood Theories and Questions: An Enigma The Grand Coulees (Upper and Lower) are widely believed to have been carved by the spectacular Missoula Floods. These colossal deluges were unleashed when the Okanagan Lobe of the Cordilleran Ice Sheet blocked the Columbia River, redirecting massive amounts of water southward. For Moses Coulee, it’s not so clear-cut. While cataract retreat due to massive floodwaters is generally assumed, most theories suggest the Okanagan Lobe effectively blocked the Missoula Floods from entering Moses Coulee. So, what carved this impressive landscape? Enter J. Harlan Bretz, the pioneering geologist who first championed the idea of colossal floods shaping the Pacific Northwest. Bretz observed a distinct wide bench within Moses Coulee, high above its floor. This led him to speculate about two distinct periods of glacial floods: An older, pre-Wisconsin “Spokane Flood” that initially carved Moses Coulee. A later Wisconsin period flood (what we now call the Missoula Floods) that deepened the coulee floor. Interestingly, current speculation suggests the Upper Grand Coulee might also owe its primary formation to these earlier “Spokane Floods,” with the Lower Grand Coulee being a product of the later Missoula Floods. It seems the story of Washington’s coulees is far more layered than once thought! Beyond Glacial Lakes: A Subglacial Hypothesis But wait, there’s another fascinating idea. Some investigators propose that Moses Coulee wasn’t carved by the well-known Missoula or Columbia glacial lake outbursts at all. Instead, they suggest outbreak floods from under the ice sheet itself. Joel Gombiner and Jerome Lesemann have explored this idea, suggesting that the immense pressure of the overlying ice lobe could have forced subglacial meltwater to flow uphill over topographic highs. This water would then have exited from under the ice, becoming the powerful floodwaters that sculpted Moses Coulee. Imagine that — floods erupting from beneath a massive glacier! Explore the Mystery Yourself The interplay between the Withrow Moraine and the unique features of Moses Coulee makes this a truly captivating area for exploration, especially for those intrigued by the raw power of ancient ice and water. To truly enhance your visit to this less-traveled gem, we highly recommend: Watching several of Nick Zentner’s insightful videos where he dives deep into these Moses Coulee questions. His engaging explanations bring the geology to life! Examining J. Harlan Bretz’s original field notes, meticulously organized in geolocated Google Maps by Glenn Cruickshank.

Palouse Falls State Park
Palouse Falls State Park, dedicated in 1951, is a 94-acre park showcasing the dramatic Palouse Falls and its unique geological history. The park is a popular destination for viewing the falls, which were formed by Ice Age floods and are a key part of the Ice Age Floods National Geological Trail. The falls were designated as Washington’s state official waterfall in 2014, thanks to the advocacy of schoolchildren from Washtucna. Palouse Falls is one of four of the last remaining year-round waterfalls on the Palouse River that once stood in the path of the ice age floods. It is rich in both geological and human history. The native Palouse Indians called it “Aput Aput” meaning “falling water.” They believed that it was created by the Great Spirit because of his displeasure with the wicked Indians who lived further upstream. This obstacle was a barrier that allowed the salmon to travel no further. Sam Fisher, a Palouse Indian, also tells the story of how four giant brothers and their giant sister used oil from beaver tails to keep their hair shiny. Needing more oil, they searched for the giant beaver and fought with him. All four falls on the river were made when the beaver slapped his tail. At the last battle at Palouse Falls, the beaver struck his tail one last time creating the falls and the bowl it falls into. The vertical cracks in the basalt were made by the claws of the beaver. Palouse Falls has made a powerful impression on all who have visited. For example, one of the fall’s earliest visitors, Laurence L. Dodd in 1867, described the site he saw this way: “just before descending the Snake River hill your eye rests on the grateful green bottom of the Palouse with its clear and pure waters, flowing into the turbid Snake and after ascending the Snake River hill to the northward and eastward, the eye sweeps over a vast extent of country rarely surpassed in rugged desolation and wildness.…” Dodd was accompanied by a few local citizens from Starbuck on horseback to witness the scene he described. Early access to the falls was either by train (many passenger trains would stop here for their passengers to look at the falls) or by coming in from the east side. Robert E. Strahorn, who built the railroad up the Palouse Canyon had the original idea of making Palouse Falls a State Park. But it was not until years later that Washtucna area resident and president of the Washtucna Community Service Club John H. Baumann really pushed the idea. In 1945, Palouse Falls State Park was created. It was dedicated on June 3rd, 1951. The 299 acres that make up the entirety of this vast park were donated by The Baker-Boyer National Bank of Walla Walla, J.M. McGregor of the McGregor Land and Livestock Company of Hooper, and Mrs. Agnes Sells, a resident of Washtucna. Palouse Falls State Park is located off Highway 261, which branches off Highway 260 out of Washtucna. The most popular season for visiting is in the spring when the river is at its highest from winter snow melt. However, each season has its own story to tell as these pictures show.

Hells Canyon Caves Reveal When it was Cut
The origin story of Hells Canyon, North America’s deepest river gorge, has long been unclear to scientists. But new research estimates it formed about 2.1 million years ago when a dramatic flood event likely created a river over the deep gorge. The researchers made the finding after studying clues hidden in the landscape and river deposits preserved in caves. They described their findings in a study published May 19 in the journal PNAS>. Hells Canyon borders Oregon, Idaho and Washington. It’s cut through by the Snake River and is North America’s deepest river gorge, at 10 miles (16 kilometers) wide and about 1.5 miles (2.4 km) deep — almost 2,000 feet deeper than the Grand Canyon. Canyons are inherently difficult to understand and date, said study lead author Matthew Morriss, a geologist at the Utah Geological Survey. “As a river erodes and carves a canyon, it sort of destroys the evidence of its own history,” Morriss told Live Science. But because Hells Canyon is so steep, he guessed it was carved quickly. To find out how the gorge formed, the team examined caves along the side of the canyon. When floods cause rivers to swell, they can deposit sediment into caves where it’s then preserved, Morriss said. The researchers analyzed gravel deposited by the Snake River in three caves along the sides of Hells Canyon, and estimated the age of the deposited material using isotope dating. This enabled the researchers to determine when the river was higher than its current level, which would have been when it was shaping the canyon. The team combined this information with the locations of knickpoints — drastic changes in river steepness where the rivers connect to the gorge — to piece together Hells Canyon’s history. These clues suggest that Hells Canyon formed when water diverted from Lake Idaho into the current route of the gorge to form what’s now the Snake River. The lake may have spilled over because of higher precipitation, or changes to the continental divide, Morriss said. This caused a river to form a path over the area that’s now Hells Canyon, and the water slowly began eroding rock about 5 million years ago, then carved the gorge much more quickly from about 2.1 million years ago. The canyon’s age was unexpected. “The age of the canyon was so much younger than I thought it would be,” Morriss said. “I had no idea it could be as young as 2 million years old — that’s younger than the Grand Canyon, which most people think could be about 5 million years old.” Hells Canyon has a lot in common with the Grand Canyon, according to Karl Karlstrom, geologist at the University of New Mexico whose work focuses on the Grand Canyon, and who was not involved with the new research. “The Grand Canyon and Hells Canyon always get compared to each other,” said Karlstrom. “They’re both big canyons with big rivers at the bottom, they’re about the same length and the same width,” Karlstrom told Live Science, but this study gives a clear picture of Hells Canyon’s distinct history. “To me this paper is a good hypothesis, and it paves the way for next generations of work,” Karlstrom said. Dating more caves in the canyon, and integrating other dating methodologies, could refine the findings and make the dates more precise, Karlstrom added. The findings can inform research on other canyons that may have been carved quickly by rivers, Morriss said. Understanding the history of Hells Canyon also gives insight into how the canyon’s formation shaped the surrounding ecosystem, as some animal species are divided by the canyon and others connected across it. Many landscape features of the southwestern U.S., like Hells Canyon and the Grand Canyon, are younger than previously expected. “[The] Western U.S. has a young and ever changing landscape that has been reshaped in the past few million years and is currently still adjusting,” Karlstrom said. This shows just how quickly — on the scale of geological time — a landscape can dramatically change, he noted. LiveScience article by Olivia Ferrari
Anthropoclastite – Rock Formed in 35 Years or Less
New research reveals industrial waste can turn into rock in as little as 35 years, instead of the thousands or millions of years previously assumed. The finding challenges what scientists know about rock formation, revealing an entirely new “anthropoclastic rock cycle.” The scientists found that waste from seaside industrial plants turns into rock especially rapidly due to the ocean water and air, which activate minerals such as calcium and magnesium in the waste, or slag, cementing it together faster than natural sediments. For a couple of hundred years, we’ve understood the rock cycle as a natural process that takes thousands to millions of years but these human-made materials are being incorporated into natural systems and becoming lithified — essentially turning into rock — over the course of decades instead. Researchers dubbed this newly discovered process the “rapid anthropoclastic rock cycle.” The findings challenge long-standing theories about how rocks form and suggest industries have far less time to dispose of their waste properly than previously thought, Owen said in the statement. The research was published April 10 in the journal Geology. Researchers discovered the first clues of turbo slag-to-rock transformation on Derwent Howe, a giant pile of waste from now-closed iron and steelmaking plants on the northwest coast of England. The scientists noticed irregular formations in these slag “cliffs,” prompting them to take a closer look. One sample contained an aluminum can tab, with a design that couldn’t have been manufactured before 1989, embedded in the material that helped the researchers estimate how long it takes for slag to lithify. For the can tab to become encased in rock, the slag must have solidified and lithified in the past 35 years. It’s possible that these processes finished earlier, so 35 years is the maximum time it takes to turn slag into rock. Scientists have previously made similar observations on the coast of Spain in the Gorrondatxe area, the researchers noted in the study, but those observations didn’t come with a time frame.
