All 20 images were the winners of the first ever annual Nature's best Photography National Parks Photo competition and were the top 20 placed images chosen from more than 3,000 entries.
Canadian photographer, Thomas Vijayan's incredible action shot of two grizzly bear siblings having a friendly fight at the Katmai National Park and Preserve, Alaska, also made the final 20 top images.
Kevin Shi of San Diego, California, whose image of Horsetail Falls in Yosemite National Park made the 20 finalists, said: 'The 'Firefall' is one of Yosemite's most well-known, amazing spectacles. Once each year in early February, the setting sun hits Horsetail Falls and illuminates the upper waterfall.
'Hundreds of photographers and tourists gather along the Merced River to witness this phenomenon.
'To shoot from a different angle, I hiked a trail up into the hills and waited until sunset.
'I was speechless when the light hit the water; the blowing wind made the glow even more incredible.'
Kristin Lindsey of Birmingham, Alabama, was shortlisted for her image overlooking Snake River, Grand Teton National Park, Wyoming.
'A four-thirty early morning wakeup call was entirely worth it to capture this sunrise as it unfolded,' she said.
'As I was en route to this location, I could tell the morning was going to have a beautiful golden glow, and the clouds behind the Grand Teton mountain range would light up and be nothing short of spectacular.
'With the moon setting (seen in far left) and the glow of the morning sun hitting the peaks and lighting up the valley below, I knew my early morning departure had been well worth the effort.'
