California’s Lassen Peak, having last erupted in 1914, is one of the more recent eruptions in the country. Today it is dormant but there is still much geothermal activity in the area. Sulphur vents, mud pots and boiling springs prove that the earth is not asleep. This view of Lassen Peak was photographed from Kings Creek in Lassen Volcanic National Park, California, USA.

The Chaos Crags are a young group of lava domes that formed 1,000 to 1,100 years ago during an instance of Holocene activity. The cluster of domes is located north of Lassen Peak and form the southernmost part of the Cascade Range of mountains. From the base of the Chaos Crags and extending toward the northwest is a rock field known as the Chaos Jumbles. This rock field was formed when the northwest slope of the Chaos Crags was undermined 300 years ago. The resulting avalanche rode on a cushion of compressed air, flattening the forest, damming Manzanita Creek and forming Manzanita Lake. The Chaos Crags are located southeast of Manzanita Lake in Lassen Volcanic National Park, California, USA.
