Abstract

The Chaos Jumbles is a rockfall avalanche deposit that was emplaced by three separate events c300 years ago. Deposits from each event are distinguishable on the basis of morphology, size variation of large dacitic surface clasts, and by the color of both the matrix and entrained dacitic blocks. The model allows calculation of deposit volumes ranging from approximately 1.2 to 1.7 x 108 m3 and also suggests that a future rockfall avalanche from the same location would have a more restricted runout than the previous events. -from AuthorsScience Applications International Corporation, Las Vegas, NV, USA.
