Sculpted by Floods Learning Resource Guide Overview Sculpted by Floods Learning Resource Guide Overview: KSPS’s Sculpted by Floods tells the story of the ice age floods in the Pacific Northwest. It is a story of the earth's power, scientific discovery and human nature - one touted by enthusiasts as the greatest story left untold. During the last ice age, floods flowing with ten times the volume of all the world's current rivers combined inundated the Northwest. What they left behind was a unique landscape that citizens of the Pacific Northwest call home. Subjects: Earth Science, Geology, History, Pacific Northwest History Grade Levels: 6-8 Materials: Lesson handouts, laptops/computers Learning Guide Objectives: Define the following vocabulary terms and use them orally and in writing: glacier, flood, cataracts, landform, canyon, dam. Analyze how floods can create landforms and shape a region’s landscape, using the Missoula Floods as a case study. Next Generation Science Standards MS-ESS2-2. Construct an explanation based on evidence for how geoscience processes have changed Earth’s surface at varying time and spatial scales. Washington State History Standards EALR 4: HISTORY: 3.1.

Integrate visual information (e.g., in charts, graphs, photographs, videos, or maps) with other information in print and digital texts. Lessons & Handouts Before the Film 1. Warm-up – Mapping Activity: Students locate and color Washington, Oregon, Idaho, and Montana on a U.S. map that displays landforms. Tell students where Missoula, Montana is located and have them label the city on the map. Next, students answer the following questions about the landform map and share their responses with a partner: What do you notice about the map? What things do the four states have in common? Why do you think they have these things in common? Do you think the geological features of these states were formed quickly or slowly? 2. Vocabulary: Ask students if they are familiar with landforms in the region (i.e., Palouse Falls, Lake Missoula, Grand Coulee, etc.). Explain that the class will soon watch segments from a documentary entitled Sculpted by Floods and explore how glaciers formed during the last ice age period and the floods they caused helped shape the landforms of the Pacific Northwest. Add that before viewing the documentary, the class will define and analyze key vocabulary terms. Using classroom dictionaries and/or online dictionaries, students complete vocabulary charts to preview and define six key vocabulary words: glacier, flood, cataracts, landform, canyon, dam. To extend this activity, have students create posters of their vocabulary charts and post them around the room for students to refer to in future lessons. 3. Pair Reading: In pairs, students read “Background on Glacial Missoula,” an informational text from the Montana Natural History Center. Afterward, they write 5 important facts they learned. Students then share their findings in a class discussion, novel ideas only. Write students’ findings on a chart paper or flip chart and post in the room for future reference. 4. Wrap-up: On sticky notes, students write the most interesting/important thing they learned in today’s lesson.

In pairs, students view the video segments for Sculpted by Floods and work together to complete the comprehension questions. Encourage students to view the segments multiple times if needed to form their responses. Rather than having pair groups answer all questions, you could have groups focus on a specific number of questions. They could then share their responses with groups who answered a different set of questions. Comprehension Questions 1. When did the last ice age occur? (12-15,000 years ago) 2. At its peak, how many cubic miles of water did Glacial lake Missoula hold? (520 cubic miles of water) 3. With how much force did the flood waters of Glacial Lake Missoula burst through the valley above Lake Pend Oreille? (Ten times greater than all the world’s present rivers combined) 4. How high did the flood waters rise? What did the waters look like? (2,200 feet, dirty—filled with sediment, ice, & jumbles of rock) 5. Where did the flood waters crash through? How many miles of land did this cover? (Northern Idaho, Washington, Columbia Gorge, Portland, Oregon, Willamette Valley, Vancouver, Oregon, Astoria, Oregon to the Pacific Ocean; 1,000 miles) 6. What are three specific ways that the ice age floods left a “unique signature” on the landscape of the Northwest? (Creation of cataracts, carving of new channels, creation of dry falls, quarried gullies and canyons—i.e., the Grand Coulee). 7. Who was J Harlen Bretz? What theory did he develop? 8. Why didn’t Bretz’s colleagues support his theory? 9. In geology, what is the difference between uniformitarianism and catastrophism? What category did Bretz’s theory fall under? 10. Who was Joseph Pardee? How is he connected to J Harlen Bretz and the story of the Missoula ice age floods? 11. How long did it take for Bretz’s theory of the floods to be accepted in the scientific community? Why did it take so long for the scientific community to accept his theory? 12. Based on your viewing of Sculpted by Floods, describe how Glacial Lake Missoula caused the flooding in the Pacific Northwest and shaped the region’s landforms.

FOREWORD Most travelers who have driven through eastern Washington have seen a geologic and scenic feature that is unique-nothing like it is to be found anywhere else in the world. This is the Channeled Scab­ land, a gigantic series of deeply cut channels in the erosion-resistant Columbia River basalt, the rock that covers most of the east-central and southeastern part of the state. Grand Coulee, with its spectac­ ular Dry Falls, is one of the most widely known features of this ex­ tensive set of dry channels. Many thousands of travelers must have wondered how this Chan­ neled Scabland came into being, and many geologists also have speculated as to its origin. Several geologists have published papers outlining their theories of the scabland's origin, but the geologist who has made the most thorough study of the problem and has ex­ amined the whole area and all the evidence having a bearing on the problem is Dr. J Harlen Bretz.

  • Chapter 85. the Example of the Lake Missoula Flood
    Chapter 85 The Example of the Lake Missoula Flood As already noted, uniformitarian hypotheses rarely, if ever, can be supported by extensive geological evidence. Part of this is due to the nature of the features, since they originated in the past. The same charge could be leveled against Flood explanations. However, geomorphological evidence for the Retreating Stage of the Flood is strong, as this ebook shows. Whereas uniformitarian scientists have to invent speculative secondary hypotheses to salvage their paradigm in the light of conflicting evidence, the Flood paradigm does not need to invent secondary hypotheses, because the evidence is consistent with the paradigm. Furthermore, the Flood paradigm has an example of how a well-substantiated catastrophic flood at the peak of the Ice Age created a water and wind gap.1 The Lake Missoula flood (earlier called the Spokane or the Bretz flood) demonstrates catastrophic floods can easily produce water and wind gaps. Figure 85.1. Glacial Lake Missoula as shown on a kiosk sign at Lake Pend Oreille. 1 Oard, M.J., 2004. The Missoula Flood Controversy and the Genesis Flood, Creation Research Society Monograph No. 13, Chino Valley, AZ. The Lake Missoula Flood One of the largest lakes ever ponded by an ice dam was glacial Lake Missoula (Figure 85.1). After this lake deepened to 2,000 feet (610 m) at the dam site in northern Idaho, the bursting ice dam initiated one of the largest floods on earth, except that described in Genesis. Glacial Lake Missoula contained 540 mi3 (2,210 km3) of water and emptied in two days.

  • The Man of Scorn
    By Jeff Reich The Man of Scorn f I asked you where the world’s largest waterfall is located, how would you reply? Would it be Inga or Kisangani Falls, both located in the Congo, or Niagara Falls, or Imaybe Victoria Falls located on the Zambezi River in Zimbabwe? Well, those are some great answers. But would you believe it is located in central Washington State in America? “What?” you might exclaim. But it is true. The only problem is, this falls has not had water running over it for centuries; thus the reason for its name — Dry Falls. Here is what Wikipedia tells us: As stated, it is around 400 feet high which at one point was estimated to “Dry Falls is a 3.5 mile long scalloped and over 3 miles long, which makes it have been up to 1,000 feet deep!

  • The Missoula Flood
    THE MISSOULA FLOOD Dry Falls in Grand Coulee, Washington, was the largest waterfall in the world during the Missoula Flood. Height of falls is 385 ft [117 m]. Flood waters were actually about 260 ft deep [80 m] above the top of the falls, so a more appropriate name might be Dry Cataract.

One lobe of the ice sheet dammed the Columbia River, creating Lake Columbia and diverting the Columbia River into the Grand Coulee. Another lobe of the ice sheet advanced southward down the Purcell Trench to the present Lake Pend Oreille in Idaho and dammed the Clark Fork River. This created an enormous Lake Missoula, with a volume of water greater than that of Lake Erie and Lake Ontario combined [530 mi3 or 2200 km3].

    Ice Age Floods Study of Alternatives Background section d BACKGROUND 1. Geologic Background n recent geological history, portions of the United States have been the site of several Imassive flooding events caused by the abrupt drainage of glacial lakes. The most dramatic of these are the Ice Age Floods, which covered parts of Montana, Idaho, Washington, and Oregon. For a better understanding of the Floods, perhaps a good place to start is to first look at the geological and climatic changes that led up to these cataclysmic floods.

BAKER Department of Hydrology and Water Resources, The University of Arizona, Tucson, AZ 85721–0011, USA (e-mail: [email protected]) Abstract: The 1920s–1930s debates over the origin of the ‘Channeled Scabland’ landscape of eastern Washington, northwestern USA, focused on the cataclysmic flooding hypothesis of J Harlen Bretz. During the summer of 1922, Bretz began leading field parties of advanced University of Chicago students into the region. In his first paper, published in the Bulletin of the Geological Society of America, Bretz took special care not to mention cataclysmic origins. However, in a subsequent paper in the Journal of Geology, to the editorial board of which he had recently been added, Bretz formally described his hypothesis that an immense late Pleistocene flood, which he named the ‘Spokane Flood’, had derived from the margins of the nearby Cordilleran Ice Sheet. This cataclysm neatly accounted for numerous interrelated aspects of the Channeled Scabland landscape and nearby regions.

    Memorial to John Everts Lamar 1897-1979 H. B. WILLMAN Illinois State Geological Survey, Champaign, Illinois 61820 John Everts Lamar was recognized internationally as a geologist and specialist in industrial minerals. For nearly 50 years he provided the people of Illinois, through their State Geological Survey, with informa­ tion about the availability and use of the industrial minerals of the State. After his retirement in 1966, he continued to share his broad knowledge of the geology of Illinois with those who followed in his footsteps, until only a few months before his death in Urbana, Illinois, on August 24, 1979, at the age of 81. “J. E.,” as he was known to associates and friends throughout the country, was an active member in several professional and scientific organizations, in­ cluding the Industrial Minerals Division and the Society of Mining Engineers of the American Institute of Mining, Metallurgical and Petroleum Engineers, the Society of Economic Geologists, the Illinois Society of Engineers, the American Ceramic Society, Sigma Xi, and the Illinois Academy of Science. He was a charter member of the Geochemical Society and a Fellow of the Geological Society of America. He received the Hal Williams Hardinge Award of the AIME in 1971. The citation reads “ For creatively conducting and directing basic and applied research directed to enhancing the utilization and development of industrial minerals, especially those native to the State of Illinois.” He also received the Distinguished Member Award of the Society of Mining Engineers and a certificate of appreciation for his participation in the development of plans showing the contribution of science to industrial development at the Chicago World’s Fair Centennial Celebration in 1933.
