A Dip in the Firehole: Yellowstone National Park, September 2003 A couple of elk refresh themselves by wading in the Firehole River.

Blowing Steam: Yellowstone National Park, September 2003 We were fortunate enough to see an eruption of Grand Geyser, the tallest predictable geyser in Yellowstone. Its eruptions can reach a height of 200 feet, and it erupts in a series of multiple bursts, anywhere from 1 to 4 at a time. Vent Geyser is the smaller geyser erupting in the foreground.
