Photos from my retro photo album titled: Lassen, CA Aug 19 – 23, 2008
Lassen Volcanic National Park is an American national park in northeastern California. The dominant feature of the park is Lassen Peak, the largest plug dome volcano in the world and the southernmost volcano in the Cascade Range. (A plug dome volcano is a type of volcano that forms when very thick and viscous lava piles up near the vent and creates a steep-sided, rounded mound. Plug dome volcanoes can erupt violently, tearing much of the mountain apart.)
The source of heat for the volcanism in the Lassen area is subduction of the Gorda Plate diving below the North American Plate off the Northern California coast. The area surrounding Lassen Peak is still active with boiling mud pots, fumaroles, and hot springs.
Nearby, is the Hat Creek Observatory, home of the SETI institute and the inspiration for the movie Contact.
My books Memory Road Trip (e-book or paperback) and Time Traveled (e-book or paperback) are both available! You can also find them at most major international book sites.
