Sulphur Works
Lassen Volcanic National Park
We stopped at the Sulphur Works where the highway crosses a hydrothermal area and we could have a quick look at steam vents and boiling mud. It stinks a bit and the rocks seem to have taken on a bright yellow in many places around it.Just off to the side of the road, a mudpot bubbles and boils quite noisily. Click here to hear it. |

The rocks are stained yellow above the stream of runoff from the Sulphur Works. |
