Weekly Photo Challenge: Monochromatic

Sulphur Works, Lassen National Park, CA

Amazing to think this boiling hole of muddy slop is only feet from the main road. You can stand on a sidewalk and peer over as long as you can stand the sulphur smell. My boys were quite unimpressed with the smell, yelling at the top of their lungs,”It stinks!”

We learned the heated source was first measured at about 80 feet below the surface but has since moved up to only 20 feet below the surface. This causes the road to melt from underneath and makes for a lot of road maintenance issues. The sounds from the mud were as wild as it looks, thumping and grunting in a rapid boil. Quite an impressive road stop.

    1. Hi, Janet. It is in Northern California in Lassen National Park. There are really cool geothermal attractions there. Similar to Yellowstone in many ways.
