California is a U.S. state on the western coast of North America. Covering an area of 163,696 sq mi (423,970 km2), California is among the most geographically diverse states. The Sierra Nevada, the fertile farmlands of the Central Valley, and the arid Mojave Desert of the south are some of the major geographic features of this U.S. state. It is home to some of the world's most exceptional trees: the tallest, most massive, and oldest. It is also home to both the highest and lowest points in the 48 contiguous states. The state is generally divided into Northern and Southern California, although the boundary between the two is not well defined. San Francisco is decidedly a Northern California city and Los Angeles likewise a Southern California one, but areas in between do not often share their confidence in geographic identity. The US Geological Survey defines the geographic center of the state at a point near North Fork, California.
Lincoln County is a county located in the U.S. state of Nevada. As of the 2010 census, the population was 5,345. Its county seat is Pioche. Like many counties in Nevada, it is dry and sparsely populated, though notable for containing the Area 51 government Air Force base.
A rain shadow is a dry area on the leeward side of a mountainous area. The mountains block the passage of rain-producing weather systems and cast a "shadow" of dryness behind them. Wind and moist air are drawn by the prevailing winds towards the top of the mountains, where it condenses and precipitates before it crosses the top. The air, without much moisture left, advances across the mountains creating a drier side called the "rain shadow".
The McMurdo Dry Valleys are a row of largely snow-free valleys in Antarctica, located within Victoria Land west of McMurdo Sound. The Dry Valleys experience extremely low humidity and surrounding mountains prevent the flow of ice from nearby glaciers. The rocks here are granites and gneisses, and glacial tills dot this bedrock landscape, with loose gravel covering the ground. It is one of the driest places on Earth and has not seen rain for nearly 2 million years.
The Wasatch Front is a metropolitan region in the north-central part of the U.S. state of Utah. It consists of a chain of contiguous cities and towns stretched along the Wasatch Range from approximately Nephi in the south to Brigham City in the north. Roughly 80% of Utah's population resides in this region, which contains the major cities of Salt Lake City, West Valley City, Provo, West Jordan, Layton, and Ogden.

Taylor Valley is the southernmost of the three large Dry Valleys in the Transantarctic Mountains, Victoria Land, located west of McMurdo Sound at approximately 77°37′S163°00′E. The valley extends from Taylor Glacier in the west to McMurdo Sound at Explorers Cove at the northwest head of New Harbour in the east and is about 29 kilometres (18 mi) long. It was once occupied by the receding Taylor Glacier, from which it derives its name. Taylor Valley contains Lake Bonney in the west (inward), and Lake Fryxell in the east (coastward), and Lake Hoare, Lake Chad, Lake Popplewell, Mummy Pond and Parera Pond close together between the two. Further east of Lake Bonney is Pearse Valley. Taylor Valley is separated from Wright Valley in the north by Asgard Range, and from Ferrar Glacier in the south by Kukri Hills.

The Whitlock Valley is a small valley in southeast Arizona, USA, lying between three mountain ranges. The valley lies on the south perimeter region of the White Mountains in eastern Arizona, and lies south of the west-flowing Gila River, and the region transitions south into Cochise County and three large valleys, with some scattered dry lakes. The valley is endorheic, with a small dry lake called Parks Lake, and merges southwest into the north of the San Simon Valley, where the San Simon River has its origins in the flatlands, and surrounding perimeter mountains. The valley was named after Captain James H. Whitlock who commanded during the Battle of Mount Gray in 1864 which was fought near the valley.
Jean Pass (north) is one of two passes on the west and northwest of the Jean Dry Lake basin, an endorheic basin bordering Jean, Nevada.
