Grand Prismatic Overlook
A short hike up a steep hill off the trail leads to this stunning view of the Grand Prismatic Spring.
Yellowstone Lake Shore
A piece of driftwood ornaments the sandy shore of Yellowstone Lake behind the Lake Village visitor's center.
The edge of Yellowstone's famous Grand Prismatic Spring steams and overflows with colorful bacteria and minerals.
A scorched tree trunk stands alone in Midway Geyser Basin along the Fairy Falls hiking trail in Yellowstone National Park.
A male elk grazes on the tall grass in the early evening along the road in the Madison area of Yellowstone National Park.
The canyons and cliff faces of Yellowstone National Park evoke a painterly aesthetic.
Through the Steam
The silhouette of a dead tree stands in a dense steam fog produced by the Artist's Paint Pots in Yellowstone National Park.
Minerals and bacteria are responsible for most of Yellowstone's incredible colors. Here, sulfur turns the ground yellow alongside chalky white gravel.
Beautiful blue water, red sand, and white gravel are commonplace in Yellowstone's geyser basins.
Yellowstone's Firehole River splashes over rocks along Firehole Canyon Drive.
Dawn, Dunraven Pass
Day breaks across the snowcapped evergreen groves of Dunraven Pass in Yellowstone National Park.
Dawn, Madison II
A fiery sunrise sets the dew-covered landscape alight in Madison on the west end of Yellowstone National Park.
The pink morning light gently kisses the clouds as thick fog rolls over the dew-covered landscape of Madison on the west side of Yellowstone National Park.
Old Faithful, Eruption
The Upper Geyser Basin's most famous and visited feature, Old Faithful spews between three and nine thousand US gallons of water into the air approximately every 90 minutes. It is a sight and sound experience that everyone should at least once have.
Sol, Yellowstone Roadside
From behind thick clouds the sun casts its warming glow upon a grove of burned trees in Yellowstone National Park.
Mammoth Hot Springs, Upper Terraces
Snow melts from the terraces of calcium carbonate at Mammoth Hot Springs where thousands of years of hot spring water create these unique formations.
Tiers from the Earth II
Terraces of calcium carbonate deposited by runoff from the Mammoth Hot Springs fill with crystal clear water and reflect the peaks of the Gallatin mountain range in the distance.
Tiers from the Earth
Unusual erosion and patterned sedimentary deposits form steps filled with glassy clear water in Yellowstone National Park.
The sedimentary deposits, heat, and chemical contents of the springs in Yellowstone sometimes cause objects laying in the pools to become coated in a hard shell.
White and red soil mingle in pools surrounding the hot springs in Yellowstone National Park.
Iron in the rock and sediment oxidizes (rusts) and provides brilliant red and orange hues to some of the Yellowstone springs.
Spring Water, Detail
A pool of blue spring water is visible in one of the many springs and outlets in Yellowstone National Park. The surrounding rock contains iron in varying stages of oxidation, giving it red and orange hues.
Muddy water is tossed into the air by steam bubbling up from underground. The water is heated by Yellowstone's caldera and boils beneath the surface.

Grand Prismatic Runoff II
The warmth of the volcanically heated water running down from the Grand Prismatic Spring area fosters the growth of multi-colored bacteria that thrive on the heat and moisture.
Near-boiling water gurgles down the rocks alongside the Grand Prismatic Spring area, giving life to a rainbow of bacteria and filling the air with thick steam.
Hot Spring, Black Sand Basin
Many of the hot springs in Yellowstone are rainbows of blue, yellow, orange, and red bacteria that thrive on the heat and moisture of the near-boiling volcanic waters.
Heated from Below
In this panoramic view of Black Sand Basin in Yellowstone National Park, you can get a sense of how the earth and water beneath your feet is literally boiling up due to the underground lava flows of the volcanic crater upon which it is situated.
Old Faithful Waits
Old Faithful is Yellowstone National Park's most famous attraction. Here, just before dawn, it quietly steams as the pressure builds up below the ground in a series of caverns, later to be sprayed sometimes up to almost 200 feet into the air.
The heat of the Grand Prismatic Spring makes it home to a rainbow of bacteria. Here, the sunlight reflecting off of the blue and orange water illuminates the steam.
Visitors, Grand Prismatic Spring
Two visitors to the Grand Prismatic Spring walk along the boardwalk suspended over the steaming hot spring waters.
A thick billow of steam rising from the volcanically heated water in the Grand Prismatic Spring area envelops a small rock formation that, if you squint, almost looks like a distant and mysterious island in the tropics.
The distant treeline is momentarily visible through the thick plumes of steam rising from the Grand Prismatic Spring.

Bison Breakfasts II
"Breakfasts," verb, to eat the morning meal. The morning meal for this lucky bison at Black Sand Basin is a selection of recently bloomed spring wildflowers.
Yellowstone National Park's volcanic crater causes water throughout the park to literally boil underground and burst forth continuously.
The Blue Deep
A warm spring heated by the volcanic crater below is filled with almost unbelievably clear, blue hued water.
During an unexpected bison migration across Yellowstone National Park, several bison crossed my path, almost too close for comfort. Their fur is thick and matted, perfect for the brutal Yellowstone winters.
Bison from Afar
We are spotted by a bison from across a clearing in Yellowstone National Park. These thousand-pound animals are dangerous but are remarkably accustomed to being observed by tourists and photographers.
