Hot spring and runoff trails at Mud Volcanoes. The steam in the background is from a large vent.
Upper Falls of the Yellowstone River from the brink of the upper falls observation platform.
Panorama of the Grand Canyon of the Yellowstone, looking toward Lower Falls from Artist Point. This shot was created by stitching 9 HDR images together and is almost 180 degrees across.

Pine trees along the Grand Canyon of the Yellowstone at Inspiration Point
Closeup of Tower Falls in early morning light. The falls drops almost 200 feet all total, but the path to the bottom was closed that morning.
Fall Aspens north of Mount Washburn.
Undine falls. Since it was in deep shadow I merged 3 shots into an HDR image.
Gardner River along the north entrance road just south of Gardner Montana.
Steaming runoff from Palette Spring. There is so much dissolved limestone in the water that the terraces can change by 20 inches a year.
Dead tree taken over by Orange Mound, in the Mammoth Hot Springs area.
Colored runoff from Angel Terrace springs, at Mammoth Hot Springs.
Pallet Spring at dusk. The colored minerals make this area look otherworldly.
Dead bushes at Palette Spring.
Dawn at Canary Springs, Mammoth Hot Springs area. The colors come from different types of bacterial that live in different temperature waters. The white areas are now dry, and so have no bacterial mats.
This area was along the road north of Roaring Mountain. It was about 25F and there was frost over all the grasses, contrasting with the steam rising from the hot spring runoff. This is a tonemapped single image trying to capture what I saw.
Looking down on the Norris Geyser Basin in early morning
An early morning shot across the Porcelain basin, with Ledge Geyser on the left side. This is a 3-shot HDR image.
This shot was taken from the West Thumb Geyser Basin, looking across Lake Yellowstone toward the north, showing the Arnica Creek fire when it was only a few acres. Big Cone geyser (extinct) is in the foreground.
Fishing Cone spring looking east across Lake Yellowstone from the West Thumb Geyser basin.
Firehole Falls on the Firehole River in western Yellowstone.
Nez Pierce creek in west Yellowstone
Fountain Geyser in the Midway Geyser Basin.
Smoke from the Arnica Creek forest fire over the Old Faithful Lodge late afternoon.
Old Faithful at sunset. I used a 3 second exposure to capture the wind-whipped wispy steam.
Upper Geyser Basin just before dawn. There are more than 100 thermal features across this basin. Old faithful is on the left.
Old Faithful geyser at dawn
Old Faithful and Lion geysers on a calm early morning.
Colorful runoff from springs in the Upper Geyser basin. The Firehole River is in the foreground.
Beehive geyser in the morning light. Beehive is unpredictable, but usually erupts at least once a day, and can shoot more than 180 feet high. The steam plume in the background is Old Faithful geyser.
Lion geyser eruption. Lion is unpredictable, but usually goes in a series of 3 events about an hour apart. I waited about 45 minutes for this one. Luckily the sun was in the right spot to give a rainbow in the geyser steam!
Sawmill geyser in the Upper Geyser basin. Although it only erupts to about 10-12 feet high, it's going almost all the time and is very close to the boardwalk.
