This tree stood along a trail I was hiking one morning. I thought the vivid, rusty bark contrasting with the greens of the moss and pines made this an interesting study of color and texture. The early morning shade provided the perfect soft, even light to produce the deeply saturated colors just as I remember seeing them.
A black bear and her two cubs look for food among fallen timber. While we watched they periodically stopped and clawed at the fallen trees. I can only assume they were after the insects inside the logs.
Pronghorn are said to be the second fastest animal on land. We were lucky enough to find a small herd of them during our visit to Yellowstone National Park and this one was practically showing off for us.
Late one evening I discovered a large colony of ground squirrels living around a tree. I woke up early the next morning and quietly walked through their territory. Doing so I began to realize the core group remained together near a tree but several individuals acted as perimeter security. This one seemed to be warning the others of my presence.
Cliff Swallows like to build their mud nests up high, out of reach of potential predators. As their name implies, they frequently nest along steep cliffs. This small colony of Cliff Swallows took advantage of the eaves of a public restroom and built their nests all along the back of the building.
The constant bubbling of mineral infused, hot water leaves colorful, thin layers of sediment throughout the geothermal areas of Yellowstone National Park. The hot spring in the foreground of this photo reminds me of a lunar crater while the colorful cliff and distant steam behind it add to the other-worldliness of the scene.
The boulders you can see in the this photograph were most likely deposited by glaciers quite some time ago. Boulders like these are pretty common throughout the glacially carved valleys and meadows in Yellowstone National Park.
Hiking past a large patch of Arrowleaf Balsamroot, I noticed a Zebra Swallowtail drifting from flower to flower collecting nectar and unwittingly spreading pollen in the process.
This bison sat resting on a hillside in Yellowstone National Park when we saw it. Since most of the bison are dark brown we nicknamed this one Blondie.
