The map shows the distribution and relationships of volcanic and surficial-sedimentary deposits in an area of Lassen Volcanic National Park and vicinity. Emphasis is on products of the eruptions of Lassen Peak and the approximately year-old eruptions of Chaos Crags. Chaos Crags is the youngest group of lava domes in Lassen Volcanic National Park, formed as six dacite domes 1,, years ago, one dome collapsing during an explosive eruption about 70 years later. The eruptions at the Chaos Crags mark one of just three instances of Holocene activity within the Lassen volcanic center. The cluster of domes is located north of Lassen Peak Location: Lassen Volcanic National Park, Shasta . The geology of the Lassen volcanic area presents a record of sedimentation and volcanic activity in the area in and around Lassen Volcanic National Park in Northern California, park is located in the southernmost part of the Cascade Mountain Range in the Pacific Northwest region of the United States.
