New Ice Age Floods Animation Brings Ancient Catastrophe to Life
An Ice Age Floods Animation Developed Through Science, Partnership, and Interpretation Imagine explaining a geological event so massive it reshaped the entire Pacific Northwest—not once, but dozens of times—across landscapes spanning four states. Now there’s a powerful new tool to help tell this remarkable story. The Ice Age Floods National Geologic Trail has just released a groundbreaking animation that brings these ancient cataclysms to life. Available now through the National Park Service and the Ice Age Floods Institute, this public-domain resource represents years of collaborative effort between scientists, educators, and park partners. Why Animation Was Essential The Missoula Floods weren’t a single disaster—they occurred dozens of times during the last ice age as ice dams repeatedly formed and failed. Each flood carved the Channeled Scablands, transported house-sized boulders, and deposited thick sediment layers across the region. The challenge? Physical evidence is scattered across vast distances, and static maps can’t capture the movement, scale, and repetition that defined these events. Visitors see individual features—coulees, erratics, deposits—without understanding how they connect to a continental-scale story unfolding over thousands of years. Animation bridges this gap by showing how ice dams failed, how floodwaters surged across landscapes, and how repeated flooding shaped what we see today. A Collaborative Achievement Scientists specializing in glacial dynamics, flood hydraulics, and geomorphology worked alongside interpreters and media specialists through multiple reviews, balancing scientific accuracy with public accessibility. The result is a flexible, modular tool designed for visitor centers, classrooms, ranger programs, and online learning. Because it’s in the public domain, partners can freely adapt segments for their specific needs—whether illustrating basalt erosion or the cumulative effects of repeated flooding. Why This Matters The Missoula Floods represent one of North America’s most dramatic geological events, yet they’ve remained difficult to comprehend. This animation finally provides a shared visual framework that makes the story accessible while honoring the complex science behind it—offering an unprecedented window into the forces that carved the Pacific Northwest.
The Pulse of Rocks
“All creatures, objects, places, and elements have a spirit.” Patrick Saltonstall, Sugpiag (Aleut) Are rocks alive? Hmm. You might be visualizing a small stone or large boulder just sitting there…doing nothing. If life has to originate from a cell, then a no vote seems reasonable. Let’s give the Mineral Kingdom a few minutes to speak on behalf of its constituents: “Our rocky friends react to temperature, expand and contract; they can absorb moisture, and they can transform their makeup entirely, like petrified wood changing into stone. Taxonomy – In the 19th . century, rocks and minerals were first classified based on their chemical make-up. As with animals and plants, new members are added yearly to the mineral kingdom’s nearly 10,000 species. Movement – Rocks sure move around, from riding glacier waves, to being catapulted for miles out of fiery volcanoes to being gently tumbled downstream by…streams, and through time, broken down into sandy beaches. Or, if you’re pumice, you can simply float downstream at your leisure. Any pebble has placed many travel stickers on its luggage finding itself in many lands during its long life. Stalagmites and stalactites check off another life form requisite by respectively growing up and down in caves with the help of slowly dripping water. Rock serves us well in concrete, road building materials, sculptures, and stone homes, all making us Salt of the Earth. Reproduction and Growth – Kidney stones are minerals and salts formed in urine. They form and grow in the bladder and kidneys. The imbalance of too many minerals in the urine and not enough liquid causes the minerals to reproduce and grow. Cooperation – Practically all living things rise out of soil, which is a mixture of organic and inorganic magic. Plants need both. Animals need minerals too. Salty seas cover a major chunk of our planet providing a swimming pool habitat to countless known and still to be known species Awe Inspiring – Rocks are the basis for our most beloved national, natural treasures, from the timeless Grand Canyon, to Yosemite’s granite walls, towering Mt. Rainier, the sandstone Arches, and the Grand Tetons, among many others. We are moved to witness sunrise and sunset light beaming red, and filtered white on mountain peaks. We climb boulders; we summit mighty bare rock and snow-covered mountains for the view, for the peace, perhaps for the love, too. The Fine Line – Everything that is living on our precious planet originated with and within the rocky world, making it a challenge to separate the line between non-life and existence. We are made of stars. We are made of star spirit. A wildlife biologist/naturalist reflects on lithologic ‘life’, Bill Weiler, January 2026

K-12 Ice Age Floods Curriculum: Floods in the Classroom
Thousands of K-12 students across the Pacific Northwest are becoming Ice Age Floods detectives—investigating ancient catastrophic flooding, conducting hands-on experiments, and sharing geological discoveries with their communities. Some may be inspired to become scientists who will ask new questions and conduct research that will advance our understanding of these ancient megafloods. This transformation is happening through Ice Age Floods Detectives, a new grade school science curriculum funded by the Ice Age Floods Institute (IAFI) and developed through partnership with the Ice Age Floods National Geologic Trail (NPS), and Engaging Every Student. The Ice Age Floods Detectives program is comprised of four phenomena-based ~1-hour lessons, targeted to grade 4 but adaptable for grades 3–8, to be taught in order over a week or more. Lesson 1: Modeling Ice Age Floods Erosion. Students create watershed models to visualize how water flows and reshapes the landscape. Lesson 2: Investigating Deposition. Students observe how different rocks and landforms are created by deposition, connecting these small-scale experiments to the massive scale of the Ice Age Floods. Lesson 3: Creating Kinesthetic Classroom Models. Students use physical movement and simple materials to model incredible scale of Ice Age flooding, weathering and erosion. Lesson 4: Exploring the Erosion Energy of Moving Water. Students experiment with water speed and volume to understand its erosive forces and to practice designing scientific experiments. Students will explore the scientific processes geologists use to make discoveries, and how the fascinating area of science—like most other disciplines—is dynamic and constantly changing. The lessons help students explore phenomena and investigate how they relate to observable geologic features. Students are gradually introduced to concepts, processes, and theories that will assist them in forming and revising their own explanations and hypotheses about the Ice Age Floods. These adaptable lessons help train students to be good scientists and critical thinkers, with a unifying theme of exploration and investigation. When the lesson plans are delivered in sequence, a storyline develops, using the creation of our NW landforms as a compelling framework to help cover core concepts and improve student skills. Numerous studies have identified the need for improved STEAM (Science, Technology, Engineering, Arts, Mathematics) education that connects to students’ lives and communities. Research indicates that grades 4-6 are particularly critical for engaging students and encouraging them to pursue STEAM fields. Those grades are a particular focus of the program, which will help us address the critical need for more scientists and engineers. The curriculum complies with Next Generation Science Standards + Common Core State Standards, and should not compete with other curricular goals for classroom time. This program updates and complements the earlier NPS Investigating Ice Age Floods K-12 curriculum. We’re bringing this curriculum to educators throughout Washington, Oregon, Idaho, and Montana through regional workshops. Ice Age Floods Institute has also established an IAFI K-12 Education Grant Program to help educators offset attendance costs and classroom implementation expenses. You can also help support the program and play a significant part in inspiring the next generation of scientists: Donate fee-free through our Zeffy Fundraiser or IAFI Gorge Chapter’s PayPal Giving Fund Share information and leads about potential funding sources— contact us at IAFIGrants@gmail.com
Malaga Landslide: Ice Age Catastrophe Along the Columbia River
The east bank of the Columbia River near Malaga, Washington, is home to one of the largest and most visually striking landslides in the Pacific Northwest: the Malaga Slide. Covering an estimated 45 square miles, this massive slope failure poured weakened basalt and sediment into the Columbia River valley at the close of the last Ice Age. Today, it remains easily visible from State Route 28, making it an accessible outdoor classroom for geology enthusiasts and tour participants. The geologic story of the Malaga Slide is a tale of both slow preparation and sudden catastrophe. Layers of basalt from the Columbia River Basalt Group were fractured and weathered over millions of years. Interspersed with weaker sedimentary layers, these formations became prone to failure. Add in groundwater saturation, the erosive power of repeated Ice Age Floods, and over-steepened valley walls, and the stage was set for a massive collapse. Scientists believe the main phase of the Malaga Slide occurred approximately 15,000–13,000 years ago, during the final stages of the Missoula Floods. While the collapse itself was sudden, the landslide likely continued to adjust and move over time, creating the hummocky terrain and displaced boulders still visible today. One of the most intriguing aspects of the Malaga Slide is its interaction with the Columbia River. Some geologists have hypothesized that the massive slide may have temporarily blocked or partially dammed the river. This could have caused short-term ponding upstream, potentially extending back toward Peshastin. Evidence of this interaction remains visible today as enormous boulders and slide debris in the river channel. Travelers heading south from Wenatchee on State Route 28 are treated to a dramatic view of the slide, with scarred slopes and scattered boulders lining the west side of the river. This visibility makes the Malaga Slide an outstanding site for guided geology tours offered by the Wenatchee Valley Erratics Chapter of the Ice Age Floods Institute. Participants learn about Ice Age Flood processes, landslide mechanics, and the long-term evolution of the Columbia River valley.

The Bowl & Pitcher at Riverside State Park
The Bowl and Pitcher is a rock formation along the Spokane River and one of the most scenic sites in the area, with basalt cliffs rising 500 feet above the river and large blocks of basalt in the river causing large rapids. The “Bowl” is a circular depression in the river and the “Pitcher” is a large detached block of highly fractured basalt. The geology of Spokane’s Bowl and Picher features dramatic basalt cliffs carved out of the flows from the Columbia River Basalt Group (CRBG), which reached this area 16 million years ago. There are river and flood deposits of sand and gravel, with granitic boulders forming terraces on the east side of the river, and huge blocks of basalt, causing the Dragon Tooth rapids, downriver from the Bowl and Pitcher. How did those rocks get there? The Spokane and Columbia rivers occupy a long, mostly bedrock canyon near the northeastern boundary of the Columbia Plateau. Glacial Lake Columbia, which formed behind the Okanogan ice lobe, occupied all of the Spokane River and a portion of the Columbia drainage basin during the last Ice Age. Then the glacial Lake Missoula outburst floods first surged over the Columbia Basin beginning around 17,000 years ago, ripping away the CRBG and other bedrock from Bayview, Idaho, to the Pacific Ocean. These floods also deposited a thick sequence of flood gravel in the valley. As Lake Columbia water level dropped, the Spokane River began to remove the sand and gravel fill. Subsequent floods continued to remove the flood deposits, leaving the basalt benches on the west side of the river and the terraces on the east side. Riverside State Park is located northwest of Spokane and consists of over 9000 acres along the Spokane and Little Spokane Rivers. The park is the second largest state park and has many recreational activities including, camping, hiking, mountain biking, horseback riding and boating (Discover Pass required). There are two view points for the Bowl and Pitcher. The first is from a small parking lot off the entrance road from Aubry White Parkway that provides an elevated view of the site. The main parking area is down along the river with a picnic area and a network of trails. From the parking lot you can follow the wheelchair accessible path across the suspension bridge over the Spokane River. From the bridge you can enjoy a view of the features that give the site its name. The original bridge was built in 1942 by the Civilian Conservation Corps. The existing bridge, based on the same plans, opened in 1998. On the west side of the river, you can access a network of trails along the river or climb up along the bluffs above the river.

Why Are Basalt Columns Mostly Hexagonal “Bestagons”
The Giant’s Causeway is a rock formation that is so otherworldly that it seems like it was made by supernatural beings. But these incredible hexagonal columns of rock aren’t the result of giant masons. They formed through a quirk of volcanic activity that shows that hexagons really are the bestagons! Cooling lava naturally creates hexagonal cracks to evenly relieve stress When lava cools and turns into rock, it contracts and builds up tension, particularly when held in place by the surrounding landscape. Just as drying mud cracks, initial cracks in the rock are random, but quickly organize into a hexagonal pattern, which scientists consider the most space-efficient shape. Note: the presentation talks about lava cooling from the top down, but it also cools upward from the bottom where it flowed onto a cooler land surface. In our area we typically see columns underlying a more chaotically fractured “entablature”. It is generally thought that because the entablature section is exposed to the air and precipitation, that results in rapid cooling that produces chaotic fracturing. The columnar section which is cooling upward from the base, would experience a much slower and more even rate of cooling, allowing it to better organize into an optimal, space-efficient “bestagonal” shape.

Missoula Chapter Field Trip TV News Coverage
Missoula chapter field trip – tv news coverage Recently the Montana Natural History Center identified a group of people new to the floods that wanted to do “something” outdoors, but not too early, or too long, or too strenuous, or too late. So IAFI’s Glacial Lake Missoula Chapter worked with the Center to put together a 4 hour, middle of the day field trip. We saved money by using the History Center short bus and our History Center liaison as our driver. Bring your own lunch and water, dress for short hikes and variable weather. The short bus limited us to twelve plus a speaker. We went for $60 per person, $40 for IAFI members, students and Natural History Center members. The trip sold out instantly as soon as we started to publicize. Chapter president Jim Shelden said, “I was surprised that much of the interest was from members that had done 1 or more trips before. The rest was from other newbies. Clearly we want to do more of this.” On trip day a reporter from the local KPAX-TV news popped in and wanted to come along, but he had to follow the bus because we were out of room. A member of The History Center board of directors also wanted to come along, so since we had no seat for him and he wanted to talk more with the reporter, he rode with the reporter. The reporter also needed to be back in town by one PM to edit and get the video ready, so we ran the trip in reverse order to get the summation speech in for our new guests to make the deadline. Then we proceeded to the other sites to show the other participants all the evidence. The day was beautiful with lunch by the river and the reviews were very good. The station got good feedback, the board member was pleased talking to the participants, and we will make the station aware of all our events in the future.
