Hanford Reach Interpretive Center and Museum
Hanford Reach Interpretive Center and Museum Ice Age Floods National Geologic Trail – Lewis and Clark National Historic Trail At The REACH Museum in Richland, Washington, you can learn about the natural and human history of the Tri-Cities. It houses rotating and permanent exhibits, including a robust exhibit on the Manhattan Project and Cold War. The REACH museum’s outdoor learning area features a sampling of the shrub steppe and riparian ecosystems and provides hands-on activities that are fun while teaching important themes like irrigated agriculture, hops cultivation, local animals, native plants, and land formation. The REACH Museum shares the natural and human history of the Tri-Cities and the surrounding area. The museum takes its name from Hanford Reach, the longest free flowing (undammed), non-tidal section of the Columbia River. The 51mile (82 kilometer) Reach marks the northern and eastern boundary of today’s Hanford Site. Its waters were critical to the site’s plutonium production mission during the Manhattan Project and Cold War. The Hanford Reach’s wild and untamed nature is a direct legacy of the Manhattan Project and the Cold War. Manhattan Project officials removed pre-war agricultural operations and prohibited further development. This formed a large security buffer surrounding the project and inadvertently preserved the shrub steppe ecosystem. When plutonium production stopped, the reduced size of the Hanford Site opened the opportunity for creation of the Hanford Reach National Monument, the US Fish and Wildlife Service’s first national monument. The REACH Museum features rotating and permanent exhibits, including robust presentations on the Manhattan Project, Cold War, indigenous peoples, and cataclysmic ice age floods. An outdoor learning area displays a sampling of the shrub steppe and riparian ecosystems and provides hands-on, interactive activities that are fun while teaching important themes including irrigated agriculture, hops cultivation, local animals, native plants, and land formation.

Grand Coulee Dam Visitor Center
Grand Coulee Dam Visitor Center Ice Age Floods National Geologic Trail | Columbia Basin Project The Columbia Basin Project, which includes Grand Coulee Dam as its main feature, is the Bureau of Reclamation’s largest multipurpose project. Grand Coulee Dam includes three major hydroelectric power generating plants and a pump generating plant. The facilities provide power generation, irrigation, flood control, stream flow regulation for fish migration, navigation, and recreation. When the final generator came online at the Nathaniel Washington Power Plant in in 1980, Grand Coulee Dam became the largest hydropower generating complex in the United States with a generating capacity of more than 6,809-megawatts supplying up to 21 billion kilowatt hours of electricity. In addition, Canada receives power under the Columbia River Treaty. Grand Coulee Dam is operated as part of a coordinated federal system of hydroelectric facilities, which provides 35% of the entire power supply of the Pacific Northwest. The Columbia Basin Project consists of 330 miles of major distribution canals, lakes and reservoirs, and about 2,000 miles of laterals that currently irrigate approximately 680,000 acres of land. In addition, Grand Coulee Dam funds a complex of three hatcheries—Leavenworth, Winthrop and Entiat—collectively known as the Leavenworth Complex, to mitigate for the loss of anadromous fish above the dam. Over 2 million spring chinook and summer steelhead are raised annually. The economic values of the Columbia Basin Project include irrigated crops valued at $1.2 billion annually, hydropower production of approximately $500 million annually, and the prevention of more than $206 million in flood damages since 1950. The Columbia Basin Project also resulted in the creation of vast wetlands and riparian areas and provides recreation benefits to about four million visitors each year. This project made the development of the Pacific Northwest possible and its importance to the nation has been profound. Its influence spread outward to benefit all citizens. Construction of Grand Coulee Dam put thousands to work during the Depression. Grand Coulee’s generators played a vital role in supplying power to build planes, ships, tanks and develop atomic energy during World War II. Following the war, the Columbia Basin Project provided opportunities for returning veterans to farm their own tracts of land. With the completion of the final generating unit in the Nathaniel “Nat” Washington Power Plant, Grand Coulees’ status as the largest hydropower generating facility in the United States was assured, and tangible benefits to Canadian residents were realized. The importance and significance of Grand Coulee Dam and the Columbia Basin Project continue to be realized today.

Fort Spokane Visitor Center
Fort Spokane Visitor Center Ice Age Floods National Geologic Trail “Fort Spokane is one of the cultural jewels of Lake Roosevelt National Recreation Area. For thousands of years, the area was a gathering place for native tribes fishing the rapids of the Spokane River. In 1880, the U.S. Army established a fort above the confluence of the Spokane and Columbia Rivers. In 1898, the military fort was closed. The buildings were then used as an Indian boarding school and tuberculosis hospital. In many ways, the Indian experience at Fort Spokane is a microcosm of the Indian experience across the United States.” Quick Facts Address: 44150 District Office Ln, Davenport, WA 99122Phone: (509) 754-7893

Lake Pend Oreille
Lake Pend Oreille Ice Age Floods National Geologic Trail The Purcell Lobe of the Cordilleran Ice Sheet repeatedly formed a 2000′ tall ice dam in this area, which backed up Glacial Lake Missoula and eventually burst catastrophically, releasing Ice Age Floods as often as about every ~10-60 years. Lake Pend Oreille is the largest lake in Idaho. The lake level is 2062 ft above sea level, with the surrounding terrain as high as 6002 ft. With a maximum depth of 1150 ft, this lake is the 5th deepest in the US. The location of the lake is probably related to an old river valley controlled by faults. The Lake Pend Oreille basin was carved by the repeated advances of Pleistocene ice and scoured by Ice Age Floods. With the waning of flood waters, the basin was filled with glacial out-wash and flood deposits. The lake is dammed at the south end by thick glacial and flood deposits that mark the beginning of the “Outburst Deposits”Quick Facts MANAGED BY:US Forest Service
Eddy Narrows
Eddy Narrows Ice Age Floods National Geologic Trail Eddy Narrows is a 10-mile long canyon between Plains and Thompson Fall along the Clark Fork River. Here all of the waters from the northern and eastern arms of Glacial Lake Missoula converged and picked up speed as they were forced through this restricted area. The steep valley walls are bare of talus and soils up to the level estimated to be the highest level of the lake (1000 ft), and there are polished grooves in the bedrock on a bench 340-400 feet above the Clark Fork River that run parallel to it. Since there is no evidence of glaciation in this area, the only explanation is the rapid draining of Glacial Lake Missoula. Using the dimensions of this flume-shaped area of the canyon, which controlled the rate of flow of water surging through it, in 1942 J.T. Pardee was able to calculate maximum speeds approaching 80 mph, emptying Glacial Lake Missoula in as little as three days. There are pullouts along MT-200 at either end of the narrowest part of this section marked for observing big horn sheep with Glacial Lake Missoula signage at the one between mileposts 59 and 60 at: 47.537940, -115.071654 Quick Facts Location:Between Plains and Thompson Falls, MT
Glacial Lake Missoula Strandlines
Glacial Lake Missoula Strandlines Ice Age Floods National Geologic Trail Imagine you are standing on the edge of glacial Lake Missoula 15,000 years ago. You can hear lapping waves cutting benches known as “strand-lines” into the shoreline. Today, you can see these huge strand-lines on hills surrounding Missoula, Montana, marking changes in lake level over time. On Mount Sentinel, marked with an “M”, and Mount Jumbo, marked with an “L”, the strand-lines are seen as horizontal lines in the vegetation or highlighted by snow in the winter. Public hiking trails switchback through the strand-lines on Mount Sentinel and Mount Jumbo. Ancient shorelines or strand-lines of Glacial Lake Missoula are visible as perfectly parallel horizontal benches on hillside slopes around Missoula. They are most visible with light snow cover, or in low evening light on the mountains marked with an”M” and an “L” on either side of Hellgate Canyon looking east from the downtown. These shoreline benches cut by wave action in the lake recorded various lake levels as the ice dam blocking the Clark Fork River far upstream on the Idaho border repeatedly failed and refilled 40 times or more. It may be that as the ice-age waned each successive ice dam that reformed was smaller and failed under less pressure from a lower lake level than the one before, leaving behind its bench as a record of the successively lower ancient lake shorelines. It’s also possible they record winter still-stands in rising lake levels over time.
