One of my first shots from my road trip through Yellowstone National Park. 7-frame HDR, processed with Dynamic Photo HDR and Photoshop. August, 2009.

The lower falls at Yellowstone National Park are 308 feet (94 meters) high, or almost twice as high as Niagara. They descend from the 590,000 year old Canyon Rhyolite lava flow and are the largest volume major waterfall in the Rocky Mountains.

I took this photo in August 2009 during my road trip through Montana and Alberta.

Beautiful shot of Canyon Falls in the Yellowstone Grand Canyon. The shot was taken at Artist Point.

While sitting in a line for two hours waiting on buffalo to cross the street in front of us, the Sun set behind the car over a beautiful river, creating a gorgeous scene that I tried to capture as well as I could. Hope you enjoy!

Yellowstone sunset near Grand Prismatic Spring (not pictured). It wasn't easy to get a shot without anyone in the frame.

I took this picture in Yellowstone National Park, at around 6am. The mist had subsided partially as the Sun came up but was reluctant to leave, lingering on the surface.

I took this at Yellowstone National Park. This is the grand canyon of Yellowstone, and although minuscule in comparison with the real grand canyon it was still a breathtaking view, the animated river snaking in between great mountains of yellow stone.

The Grand Prismatic Spring in Yellowstone National Park is the largest hot spring in the United States, and the third largest in the world.

The vivid colors in the spring are the result of pigmented bacteria in the microbial mats that grow around the edges of the mineral-rich water. The bacteria produce colors ranging from green to red; the amount of color in the microbial mats depends on the ratio of chlorophyll to carotenoids and on the temperature of the water which favors one bacterium over another. In the summer, the mats tend to be orange and red, whereas in the winter the mats are usually dark green. The center of the pool is sterile due to extreme heat.

The deep blue color of the water in the center of the pool results from the intrinsic blue color of water, itself the result of water's selective absorption of red wavelengths of visible light. Though this effect is responsible for making all large bodies of water blue, it is particularly intense in Grand Prismatic Spring because of the high purity and depth of the water in the middle of the spring.

The spring is approximately 250 by 300 feet (80 by 90 m) in size and is 160 feet (50 m) deep. The spring discharges an estimated 560 US gallons (2,100 L) of 160 F (70 C) water per minute.
