Lassen Volcanic National Park is a living museum of vulcanism. It contains all four of the world's known types of volcanoes - stratovolcanoes, volcanic domes, shield volcanoes, and cinder cones. And there are various types of hot springs, geysers, fumaroles, vents, and other geothermal features.
At about 7000 foot altitude, Sulphur Works is one of the primary geothermal areas within the park. It features fumaroles, mudpots, hot steam, boiling water, and other geothermal features, including the ever-present hydrogen sulfide gas. The surface is composed of andesite rock.
The Sulfur Works, a bright yellow patch in Lassen Volcanic Park, is the core of Mt Tehama which was once 11,000 feet high. The sulfur pots stink - and are indeed dangerous. They boil and bubble, and one can easily imagine how awful it would be to step through the earth and into that gray goo. Yet the colors of the covering landscape are wonderfully subtle shades of pewter, gold, and browns.
Lassen Volcanic National Park is best described as weird, unusual, spectacular, fun, beautiful, majestic, wild, somewhat surreal and challenging.
