Toketee Falls
Toketee Falls is a waterfall in Douglas County, Oregon, United States, on the North Umpqua River at its confluence with the Clearwater River. It is located approximately east of Roseburg near Oregon Route 138. ''Toketee'' (pronounced TOKE-uh-tee), is a Chinook Jargon word meaning "pretty" or "graceful". The falls was officially named by a United States Board on Geographic Names decision in 1916, over alternate names Ireland Falls and Toketie Falls. Description Carved from ancient columnar basalt, Toketee Falls drops approximately in two stages. With a reliable water flow on the North Umpqua River, the falls avoids the seasonal fluctuations of other creek-fed waterfalls in Oregon. Hydropower plant The waterfall is regulated by a dam built just upstream by PacifiCorp PacifiCorp is an electric power company in the western United States.

Yarmouth, Maine
Yarmouth is a town in Cumberland County, Maine, United States, twelve miles north of the state's largest city, Portland. When originally settled in 1636, as North Yarmouth, it was part of Massachusetts, and remained as such for 213 years. In 1849, twenty-nine years after Maine's admittance to the Union as the twenty-third state, it was incorporated as the Town of Yarmouth. Yarmouth is part of the Portland– South Portland-Biddeford Metropolitan Statistical Area. The town's population was 8,990 in the 2020 census. The town's proximity to the Atlantic Ocean, and its location on the banks of the Royal River (formerly ''Yarmouth River''), which empties into Casco Bay less than one mile away, means it is a prime location as a harbor. Ships were built in Yarmouth's harbor mainly between 1818 and the 1870s, at which point demand declined dramatically. Meanwhile, the Royal River's four waterfalls within Yarmouth, whose Main Street sits about above sea level, resulted in the foun ...

Dams In Oregon
A dam is a barrier that stops or restricts the flow of surface water or underground streams. Reservoirs created by dams not only suppress floods but also provide water for activities such as irrigation, human consumption, industrial use, aquaculture, and navigability. Hydropower is often used in conjunction with dams to generate electricity. A dam can also be used to collect or store water which can be evenly distributed between locations. Dams generally serve the primary purpose of retaining water, while other structures such as floodgates or levees (also known as dikes) are used to manage or prevent water flow into specific land regions. The earliest known dam is the Jawa Dam in Jordan, dating to 3,000 BC. The word ''dam'' can be traced back to Middle English, and before that, from Middle Dutch, as seen in the names of many old cities, such as Amsterdam and Rotterdam. History Ancient dams Early dam building took place in Mesopotamia and the Middle East. Dams were used ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Basalt
Basalt (; ) is an aphanite, aphanitic (fine-grained) extrusive igneous rock formed from the rapid cooling of low-viscosity lava rich in magnesium and iron (mafic lava) exposed at or very near the planetary surface, surface of a terrestrial planet, rocky planet or natural satellite, moon. More than 90% of all volcanic rock on Earth is basalt. Rapid-cooling, fine-grained basalt is chemically equivalent to slow-cooling, coarse-grained gabbro. The eruption of basalt lava is observed by geologists at about 20 volcanoes per year. Basalt is also an important rock type on other planetary bodies in the Solar System. For example, the bulk of the plains of volcanism on Venus, Venus, which cover ~80% of the surface, are basaltic; the lunar mare, lunar maria are plains of flood-basaltic lava flows; and basalt is a common rock on the surface of Mars. Molten basalt lava has a low viscosity due to its relatively low silica content (between 45% and 52%), resulting in rapidly moving lava flo ...

United States Board On Geographic Names
The United States Board on Geographic Names (BGN) is a federal body operating under the United States Secretary of the Interior. The purpose of the board is to establish and maintain uniform usage of geographic names throughout the federal government of the United States. History On January 8, 1890, Thomas Corwin Mendenhall, superintendent of the US Coast and Geodetic Survey Office, wrote to 10 noted geographers "to suggest the organization of a Board made up of representatives from the different Government services interested, to which may be referred any disputed question of geographical orthography." President Benjamin Harrison signed executive order 28 on September 4, 1890, establishing the ''Board on Geographical Names''. "To this Board shall be referred all unsettled questions concerning geographic names. The decisions of the Board are to be accepted y federal departmentsas the standard authority for such matters." The board was given authority to resolve all unsettled ques ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Waterfall
A waterfall is a point in a river or stream where water flows over a vertical drop or a series of steep drops. Waterfalls also occur where meltwater drops over the edge of a tabular iceberg or ice shelf. Waterfalls can be formed in several ways, but the most common method of formation is that a river courses over a top layer of resistant bedrock before falling on to softer rock, which Erosion, erodes faster, leading to an increasingly high fall. Waterfalls have been studied for their impact on species living in and around them. Humans have had a distinct relationship with waterfalls for years, travelling to see them, exploring and naming them. They can present formidable barriers to navigation along rivers. Waterfalls are religious sites in many cultures. Since the 18th century they have received increased attention as tourist destinations, sources of hydropower, andparticularly since the mid-20th centuryas subjects of research.
