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.

Megaflood Adventure Section 3
Gingko Petrifed Forest Vantage, Washington Petrifcation is a process where trees and wood are turned to stone. The trees are buried and protected from natural forces, transforming the wood to solid rock over huge amounts of time. Most of the wood you see at Gingko is from the Missoula Floods, so you can see how the trees looked 13,000 years ago! Take the The Trees of Stone Interpretive Trail 2 miles west of the Visitor Center. On the trail you’ll see lots of fossils, erratics, and petrifed logs. Pick your favorite thing and draw it! BONUS: Gingko Petrifed Forest has its own Junior Ranger program. Complete it to earn another badge! Palouse Falls State Park Lacrosse, Washington Long before the foods, tectonic forces stressed the basalt bedrock and opened deep fractures. The megafoods took advantage of these weakened areas and used them to change the course of the river. Palouse Falls has many of these cracks in the canyon walls. How many can you fnd?

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. -

Although similar features occur in the scablands of eastern Washington, the currents there were channeled floods that flowed downhill; here the sublake currents often flowed uphill. Similar catastrophic lake-bottom currents have been documented elsewhere only in the Altai flood of Siberia. When the ice dam failed and flooding began, the northern rim of the Camas Prairie Basin and part of the eastern rim were under water, forming sublake divides, or ridges. All flow into the basin came over the basin rims, and all of the lake-bottom currents were flowing uphill to enter the basin. -
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]. -
1. Geologic Background
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.

Chamness January 2007 Prepared for CH2M HILL Hanford Group, Inc., and the U.S. Department of Energy under Contract DE-AC05-76RL01830 Pacific Northwest National Laboratory Richland, Washington 99352 Foreword This data package discusses the geology of the single-shell tank (SST) farms and the geologic history of the area. The purpose of this report is to provide the most recent geologic information available for the SST farms. This report builds upon previous reports on the tank farm geology and Integrated Disposal Facility geology with information available after those reports were published. Both metric and English units of measurement are used in this document. However, English units are used for descriptions and discussions of drilling activities and samples because that is the system of units used by drillers to measure and report depths and well construction details. To convert feet to meters, multiply by 0.3048; to convert inches to centimeters, multiply by 2.54; to convert meters to feet, multiply by 3.28. iii Acknowledgments The authors acknowledge Frederick M.
