USA(Georgia) - Atlanta

Atlanta  is the capital of and the most populous city in the US state of Georgia. Atlanta encompasses 132.4 square miles (342.9 km²), of which 131.7 square miles (341.1 km²) is land and 0.7 square miles (1.8 km²) is water. The city is situated among the foothills of the Appalachian Mountains, and at 1,050 feet (320 m) above mean sea level, Atlanta has the highest elevation of major cities east of the Mississippi River. Atlanta straddles the Eastern Continental Divide, such that rainwater that falls on the south and east side of the divide flows into the Atlantic Ocean, while rainwater on the north and west side of the divide flows into the Gulf of Mexico. Atlanta sits atop a ridge south of the Chattahoochee River, which is part of the ACF River Basin. Located at the far northwestern edge of the city, much of the river's natural habitat is preserved, in part by the Chattahoochee River National Recreation Area.
Monument Valley (Navajo: Tsé Biiʼ Ndzisgaii, meaning valley of the rocks) is a region of the Colorado Plateau characterized by a cluster of vast sandstonebuttes, the largest reaching 1,000 ft (300 m) above the valley floor. It is located on the Arizona-Utah state line near the Four Cornersarea. The valley lies within the range of the Navajo Nation Reservation and is accessible from U.S. Highway 163. The area is part of the Colorado Plateau. The elevation of the valley floor ranges from 5,000 to 6,000 feet (1,500 to 1,800 m) above sea level. The floor is largelysiltstone of the Cutler Group, or sand derived from it, deposited by the meandering rivers that carved the valley. The valley's vivid red color comes from iron oxideexposed in the weathered siltstone. The darker, blue-gray rocks in the valley get their color from manganese oxide.
