Photographs from U.S. Department of the Interior's Instagram account reveal the stunningly diverse landscapes
The U.S. Department of the Interior has amassed a breathtaking collection of photography documenting the diverse landscapes of the United States and shared it in an Instagram account.
The images come from photographers around the country who have captured moments in time in public lands, such as national parks, to dramatic effect. The account has also captured 30,000 followers with its depictions of U.S. natural beauty.
The Department of the Interior is charged with managing America's vast natural and cultural resources, and employs about 70,000 people around the country to do just that. Under the umbrella of the Department are the Bureau of Indian Affairs, the Bureau of Land Management and the U.S. Fish and Wildlife Service.
Below are 21 of the most beautiful shots to grace the Department's Instagram page since it was begun about a year ago. Follow the Department of the Interior for more amazing pictures from around the country.

It is one of America’s greatest natural wonders – a spectacular scar in the dusky soil of Arizona that ranks as one of the best-known landmarks on the planet.
Indeed, show most people a photograph of the Grand Canyon, and they should recognise it instantly – those steep cliffs falling away to the silver ribbon of the River Colorado far below; the Canyon walls dancing through a rainbow of pinks, reds, oranges and browns.
So it is rare to see photographs that capture this geographical glory in a less-seen light. But the images here manage that. The pictures show the less-visited Havasu Canyon, which flows north into the Colorado immediately to the west of the portion of the national park which plays host to the majority of tourists.
Havasu Canyon is part of the adjacent Havasupai Indian Reservation. And while it is also accessible to the public, it does not receive the footfall of the main national-park space.
The photos show a snapshot of waterfalls within this smaller canyon; the large, double-chuted Havasu Falls and the smaller Mooney Falls – as well as the almost hidden Royal Arch Creek Falls, which is part of Grand Canyon National Park.
All can be visited, although plenty of leg-work and hard hiking is required to reach the more off-path spots.

Water at its most wonderful: This breathtaking image captures Havasu Falls - the main cascade on Havasu Creek in Arizona
A different take on the theme: Depending on the volume of water, Havasu Falls splits into two distinct torrents
Come take a look at all this beauty: Havasu Falls sits on the Havasupai Indian Reservation, but is accessible to the public
One for the intrepid: Mooney Falls also lies within the Havasupai Indian Reservation - and offers a subtler form of beauty to the main Havasu Falls
Beyond the obvious: Although the Grand Canyon is one of the most recognisable landmarks on the planet, it still offers corners and areas that can surprise
Tucked away: The National Park Service describes Royal Arch Creek Falls as a 'top-drawer canyon adventure, replete with more natural beauty than humans can absorb'
As it looks on a normal day: A more usual shot of the Grand Canyon, as seen by thousands of people every year
Standing at the edge of the Grand Canyon is always a breath-taking experience but a new photo taken from the International Space Station shows that it is just as awe-inspiring from space.
The latest image, which show the full expanse of the Grand Canyon as it cuts through the Kaibab Plateau, was taken by the Expedition 39 crew on March 25, as they orbited Earth.
The photo shows the Colorado river, marked as a dark line snaking its way through the canyon's floor, as well as the forested areas along the north and south sides, which make up one of several vital eco-systems in the park.
Awe-inspiring: The jagged path of the Grand Canyon can be seen in this image taken by a crew on board the International Space Station
Jagged ridges rising above the surrounding arid landscapes also clearly mark out the 277-mile canyon, which was formed about 6 million years ago due to a combination of tectonic uplift and the Colorado river changing its course.
Just as the Grand Canyon, with its 1.6km drop through sandstone and limestone, is a popular tourist attraction, bringing in up to 5 million visitors a year, it is also a popular landmark with Nasa's astronauts, who enjoying photographing it from the space station. The six-man Expedition 39 crew are part of a mission that provides photos of Earth to help scientists and geologists with their research, as well as amazing the general public.
Their photos, which show rock formations, wild storms and erupting volcanoes, can be viewed on the Earth Observatory website.
Revealing: Astronauts regularly take pictures of the Grand Canyon to help scientists and geologists with their research
Artistic: In some of Nasa's images, such as this one, the ridges of the canyon look like the arteries of a heart
Out of this world: The Earth's atmosphere can be seen alongside the canyon in this image of the natural wonder
Grounded: Even when viewed from Earth, the colors and shapes of the Grand Canyon are amazing to look at
Sightseeing: The Colorado river can clearly be seen in this image taken by Italian astronaut Paolo Nespoli in 2010
'It's a lot easier than taking pictures from a car!' Stunning images taken by intrepid explorer from his tiny plane... by sticking his camera out the cockpit window.
These are the stunning images of everyday life taken by photographer Alex MacLean from his small Cessna plane hundreds of feet in the air.
The incredible aerial photography includes everything from sun-drenched bathers on an Italian beach, to technicolor fields of flowers in California and housing blocks in the arid Las Vegas desert.
Maclean, 66, takes the photographs from hundreds of feet in the air by sticking his camera out the cockpit window of his tiny Cessna 182 whenever he comes across a scene worth documenting.
Surreal: This photograph by Alex MacLean shows a large housing estate in the middle of the desert outside Las Vegas. The 66-year-old takes the photographs from hundreds of feet in the air by sticking his camera out the cockpit window of his tiny Cessna 182 plane
Stunning: This 1989 shot shows colorful flower fields near Carlsbad in California. Aerial photography is 'a lot easier than taking pictures from a car' according to MacLean

Massachusetts-based MacLean has been taking photographs from planes since graduating from Harvard and gaining a pilot's license in 1975.
His photography career began with selling functional architectural and landscape images to universities, before deciding to focus on more aesthetically pleasing, artistic images.
Thanks to the angle from which MacLean takes his shots, even the must mundane objects appear abstract and surreal.
Simple boats tethered in a Chicago dock, or spectators' cars parked at a Nascar event in Virginia, look almost as if they have been deliberately placed, such is the clarity and colour MacLean manages to capture.
This photograph of a boat yard in Newport, Virginia was taken in 2011. Alex MacLean's aerial shots can make everyday images appear surreal and abstract
Spots: This image of boats in Tremont, Maine almost looks like a painting thanks to the solid background and the bright decoration and fairly even spacing of the boats

Complex: The bright and busy image is in fact an aerial view of the Ocean City Amusement Park in Ocean City, Maryland
Catching a wave: This perfectly-timed photograph by Alex MacLean shows seven surfers enjoying the water off Sunset Beach in Oahu, Hawaii
In his work, MacLean battles unpredictable weather and fights to take steady pictures over the vibration of the plane.
But he believes advances in technology during his 30-year career have definitely made some aspects easier.
'When I started out, there wasn't even auto focus,' he said.
'When you think of auto exposure, that's a big thing. Of course, the biggest change was transitioning to digital photography, which had lots of advantages,' MacLean added.
