Photo by @Amivitale for National Geographic Traveler. Montana: Where the Locals Go. The Upper Missouri River in #Montana is one of the best canoe trips in the Unites States. It runs for 149 miles through a spectacular canyon incised into the prairie country of central Montana. Up river from where we set off is "Decision Point", where Meriwether Lewis and William Clark found the confluence of the Missouri River with the Marias River. They now faced a crucial question: Which river was the Missouri? Their entire party felt that they should follow the Marias River while Lewis and Clark decided continuing along the Missouri was the correct route. The captains noted that the south fork was clearer, smoother, and more rapid, and its bottom was "composed of round and flat smooth stones like most rivers issueing from a mountainous country." This was one of the first true tests of their ability to lead and make good decisions. #inmontana #montanamoment #onassignment #Nikonusa #d4s #Nikon #nikonambassador @natgeo @natgeocreative @thephotosociety #photojournalism #nofilter #photojournalism #amivitale #latergram #journalism #canoeing

Rackwick Bay on the Orkney island of Hoy has a fine boulder-strewn beach that can be quite haunting. People living here 5,000 years ago found these islands a rich place to live during the age of the great stone circles that dot this land. Shot on assignment for National Geographic's story on Orkney and the incredible story of stone age life in this month’s issue, August 2014.

Comet C/2013 UQ4 (Catalina) has been observed by NASA’s Near-Earth Object Wide-field Infrared Survey Explorer (NEOWISE) spacecraft just one day after passing through its closest approach to the sun. The comet is seen glowing brightly in infrared wavelengths on July 7, 2014, with a dust tail streaking more than 62,000 miles (100,000 kilometers) across the sky. Its spectacular activity is driven by the vaporization of ice that has been preserved from the time of planet formation 4.5 billion years ago. C/2013 UQ4 takes more than 450 years to orbit the sun once and spends most of its time far away at very low temperatures. Its orbit is also retrograde, which means that the comet moves around the sun in the opposite direction to the planets and asteroids. The comet was originally thought to be an asteroid, as it appeared inactive when discovered by the Catalina Sky Survey on October 23, 2013. NEOWISE also observed the comet to be inactive on New Year's Eve, 2013, but since then the comet has become highly active, allowing astronomers around the world to observe it. The comet's activity should decline as it once again returns to the cold recesses of space. Image Credit: NASA/JPL-Caltech #nasa #neowise #comet #asteroid #infrared #stars #space

The six-person Expedition 40 crew wrapped up a productive week of cargo vehicle traffic and science aboard the International Space Station with more medical studies, physics and robotics on Friday. Meanwhile, preparations continue for the launch of another station resupply vehicle next week. Seen here is one of the more spectacular scenes of the Aurora Borealis that was photographed by one of the space station crew members aboard the International Space Station from an altitude of approximately 223 nautical miles.

Today marks the 2 year anniversary of the Opening Ceremony of the London 2012 Olympic Summer Games #londonlegacy

Yesterday, astronaut Reid Wiseman shared this image of Earth showing Italy at night from the International Space Station tweeting "I looked on in awe and was rendered speechless by so much beauty." The Expedition 40 crew has been hard at work 260 miles above us in the floating laboratory. They set a new record for #ISS research completed in a week -- 82 hours -- this past week. Image credit

On March 11th of this year, using his authorities under the Antiquities Act, President Obama designated the Point Arena-Stornetta Unit, protecting approximately 1,665 acres of a significant and spectacular stretch of public lands along the Mendocino coastline in Northern California. I was here just before this, on assignment for a story celebrating the 50th anniversary of the Wilderness Act. Look for the article in Nat Geo in the September issue. #wilderness #california #weather #nature #@natgeo @thephotosociety

A landscape of sheer cliffs towering 1,000 feet above a ribbon of blue water. World class fishing and a place where wild horses still run free. Bighorn Canyon National Recreation Area in Montana is a place where imagination meets reality. Bighorn Canyon has unrivaled recreation possibilities. Bighorn Canyon sunrise, July 2012. Thanks to visitor Phil Seu for letting us use his stunning photo!
