Old Faithful Geyser erupting under a half moon. With long exposures, the steam produces so interesting forms.
Winter in the Grand Canyon of the Yellowstone.
One of my favorite animals in Yellowstone, the bobcat. Nearly every winter for at least the past 10 years, at least one bobcat has been seen on the west side of the park. I was on an afternoon wildlife tour that travels the west side of the park looking for wildlife. I knew a bobcat had been seen with some regularity in one of the areas we were going to be travelling on the tour so I was already intently looking when I caught a glimpse of a brown animal at the base of a tree along the Madison River. I called out that I'd seen something, but I didn't know what I saw. After a few tense moments, I caught sight of a pair of ear tufts peeking above the snowbank along the edge of the river. The bobcat seemed well aware of the crowd that eventually gathered, but appeared unconcerned.
