The next two images are from the Beartooth Mountains. This is a mountain group northeast of Yellowstone. The highway over these mountains is consistently ranked as one of the top-10 scenic drives in the country. It hits a high point of nearly 11,000 ft.

Hmm, must be where the name came from. I got this shot by walking down the "Uncle Tom" trail, which was long and steep, including about 400 stair steps. And at 8000 ft elevation, it takes it out of you (well, it took it out of my 45-yr old lungs).
Nikon D70s, Sigma 10-20mm, set at 12mm, 1/640 sec @ f/9, ISO 320.Old Faithful. I took this with my big zoom, standing way far back, because I wanted the "compressed" look that a telephoto lens gives an image. It makes the people look closer to the geyser than they really are. I thought I was back far enough to get the whole thing in the frame, but unfortunately was not. But even with the top cut off, you can still tell just how big the geyser is.
