Spectacular landscapes
Spectacular images of people exploring the United States' most awe-inducing vistas and starlit night skies prove just how amazing this big country is.
The stunning shots range from landscapes showing people dwarfed by the sheer size of huge mountains and rocks to skyscapes of the Milky Way.
David Swindler, an American photographer and owner of Action Photo Tours, based in Kanab, Utah, took the photographs.
They include an array of locations, including the Grand Canyon; Vermillion Cliffs, Ariz.; and Zion National Park. (Caters News)
