Yellowstone National Park: action from a boardwalk

The park has well laid out boardwalks that meander around the thermal basins.

Fumaroles and bubbling hot springs are a constant.

We have been so fortunate to be walking on a boardwalk as a geyser erupts.

As did Vixen Geyser in the Norris Geyser Basin.

She is a perfect rock vent, which looks man-made in its symmetry. The geyser vent fills up and drains much like a toilet, and in between erupts with style.

Each water drop was gleaming in the late afternoon sun.

Fabulous Vixen Geyser.
