Title: Saw Kill
Passage: Saw Kill may refer to three different bodies of water in New York. Two are tributaries and make up watersheds on the eastern bank of the Hudson River. The northernmost of these is in the Town of Stuyvesant, New York in Columbia County and the southernmost of these is in the Town of Red Hook, New York in Dutchess County. The northern Saw Kill is more commonly known as Mill Creek today. The third tributary drains into Esopus Creek on the Hudson’s west bank. This article refers to the southern body of water on the east bank as Saw Kill (east) and the body of water on the west bank as Saw Kill (west).
Title: Grand Canyon
Passage: U.S. President Theodore Roosevelt visited the Grand Canyon in 1903. An avid outdoorsman and staunch conservationist, Roosevelt established the Grand Canyon Game Preserve on November 28, 1906. Livestock grazing was reduced, but predators such as mountain lions, eagles, and wolves were eradicated. Roosevelt along with other members of his conservation group, the Boone and Crockett Club helped form the National Parks Association, which in turn lobbied for the Antiquities Act of 1906 which gave Roosevelt the power to create national monuments. Once the act was passed, Roosevelt immediately added adjacent national forest lands and redesignated the preserve a U.S. National Monument on January 11, 1908. Opponents such as land and mining claim holders blocked efforts to reclassify the monument as a U.S. National Park for 11 years. Grand Canyon National Park was finally established as the 17th U.S. National Park by an Act of Congress signed into law by President Woodrow Wilson on February 26, 1919.
Title: Thistle, Utah
Passage: Thistle is a ghost town in Spanish Fork Canyon in southeastern Utah County, Utah, United States. During the era of steam locomotives, the town's primary industry was servicing trains for the Denver and Rio Grande Western Railroad (often shortened to D&RG, D&RGW, or Rio Grande). The fortunes of the town were closely linked with those of the railroad until the changeover to diesel locomotives, when the town started to decline.

Title: Grand Canyon
Passage: Nearly two billion years of Earth's geological history have been exposed as the Colorado River and its tributaries cut their channels through layer after layer of rock while the Colorado Plateau was uplifted. While some aspects about the history of incision of the canyon are debated by geologists, several recent studies support the hypothesis that the Colorado River established its course through the area about 5 to 6 million years ago. Since that time, the Colorado River has driven the down - cutting of the tributaries and retreat of the cliffs, simultaneously deepening and widening the canyon.

Title: Forward Harbour
Passage: Forward Harbour was a cannery town in the Johnstone Strait region of the Central Coast of British Columbia, Canada, located on the inlet of the same name, which is on the mainland side of Wellbore Channel, to the east of Hardwicke Island. Nearby on the same vicinity on the Mainland, though fronting on other bodies of water, are Jackson Bay to the immediate north, off Sunderland Channel, and Heydon Bay, British Columbia to the east on Loughborough Inlet.
Title: Melas Chasma
Passage: Melas Chasma is a canyon on Mars, the widest segment of the Valles Marineris canyon system, located east of Ius Chasma at 9.8°S, 283.6°E in Coprates quadrangle. It cuts through layered deposits that are thought to be sediments from an old lake that resulted from runoff of the valley networks to the west. Other theories include windblown sediment deposits and volcanic ash. Support for abundant, past water in Melas Chasma is the discovery by MRO of hydrated sulfates. In addition, sulfate and iron oxides were found by the same satellite. Although not chosen as one of the finalists, it was one of eight potential landing sites for the "Mars 2020" rover, a mission with a focus on astrobiology.
