 Lassen Volcanic National Park Guide on CompassMonkey.com
Chaos Crags and Devastated Areas are two separate areas separated by about 15 or 20 miles but they are both similar in appearance and were created as a result of the 1915 Lassen explosion.
Chaos Crags was created by an air cushion avalanche.
This was created when rocks and magma mixed with snow, ice and vegetation came hurtling down the slopes at an incredible velocity, removing and killing everything in its way.

 Changes at Oldoinyo Lengai between 1993 and 1998
Contrast the flow across the centre of Saunders' photo, which is long and very thin (probably less than 50 cm thick) with the corner of Chaos Crags just visible on the left side of the photo.
Since this photo was taken in February 1996 the whole of Chaos Crags has been covered by younger pahoehoe flows.
One small blocky flow similar in appearance to Chaos Crags was extruded in 1996 (look back at the figure on the natrocarbonatite page) but it became covered by younger lavas before it could be sampled and analysed.

 CHAOS BLOOD BOWL TEAMS - Citadel Journal / Blood Bowl Compendium article
It is the Chaos Warriors who play in the wider leagues, and they take the best players from the tribes to aid them on the field.
Whilst playing, if there are no Chaos Warriors on the pitch, all Marauders play at -1 MA and -1 AG (to a minimum of 1) to represent the ill discipline that creeps in without the steadying influence of a Chaos Warrior.
No one played any less than three Chaos Warriors in their teams just to safeguard against the effectiveness of their Marauders slipping should all the Chaos Warriors be killed or injured.

 Lassen Volcanic National Park - The Eruption of Lassen Peak (U.S. National Park Service)
The most recent eruptions in the Lassen area were the relatively small events that The Chaos Crags, a group of six lava domes, was formed about 1,100 years ago in the latest large eruptions to occur in the area of occurred at Lassen Peak between 1914 and 1917.
However, the geologic history of the Lassen area indicates that volcanism there is episodic, having periods of relatively frequent eruptions separated by long quiet intervals.
For example, the last large event before the Chaos Crags eruption was the one that built Lassen Peak 27,000 years ago.

 Howstuffworks "Lassen Volcanic National Park Visitor Information"
This national park is a churned-up landscape of stark features that have been given such descriptive names as Chaos Crags and Chaos Jumbles.
Yet throughout the park, cinder crags and magma canyons continue to offer proof of former violence, while gurgling thermal features suggest the possibility of a fiery future.
As is also true of a large portion of northern California, the park is covered with deep snow for much of the year, which has had the effect of producing several beautiful lakes.

 Database for the geologic map of the Lassen Peak, Chaos Crags, and upper Hat Creek area, California
This database was constructed in order to produce a geologic map as a basis for understanding processes involved in the explosive eruptions of Lassen Peak and Chaos Crags and for producing a volcano-hazards assessment of the Lassen Peak area.
The scale of the source map limits the spatial resolution (scale) of the database to 1:24,000 or smaller except in the area of a 1:2,500 inset map of the Lassen Peak summit area.

The Devastated Area evidences the combined mud flow and gas blast destruction typical of many volcanic eruptions in the Cascades.
The Chaos Jumbles area looks similarly destroyed, but for a different reason.
An air-cushioned avalanche - one that fell so rapidly en masse that it trapped and compresses air beneath itself - crashed down the Chaos Crags about 300 years ago.

 Molossian Institute of Volcanology - Lassen Volcanic National Park
The Cinder Cone complex NE of Lassen Peak was erupted in a single episode several hundred years before present and is considered part of the Lassen volcanic center.
When Lassen Peak formed, it looked much like the nearby 1,100-year-old Chaos Crags Domes, with steep sides covered with angular rock talus.
However, from 25,000 to 18,000 years ago, during the last ice age, Lassen's shape was significantly altered by glacial erosion.

 Chaos Crags   (Site not responding. Last check: 2007-10-09)
Chaos Jumbles, a massive debris avalanche from a series of dacite domes (Chaos Crags) north of Lassen Peak, Lassen Volcanic National Park, California.
The domes formed by extrusion of viscous magma, and tend to be very steep.
These avalanches occurred around 1600 A.D. The Park Service wisely moved a visitor center and campground from this area.

 The activity of Oldoinyo Lengai in 1993
Analysis of Chaos Crags showed it to be very rich in crystals of nyerereite and gregoryite, the typical minerals of natrocarbonatite.
However it also contained 8 to 10% by weight of spheroids (up to 2 mm in diameter) of dominantly silicate material.
This unusual composition may be related to the very high viscosity of Chaos Crags and another flow formed at the same time.
