Dating and recurrence frequency of prehistoric mudflows near Big Sur, Monterey County, California
Botanical evidence based on the dendrochronology and root horizons of redwoods ( Sequoia sempervirens ) and radiocarbon dating were used to date prehistoric mudflows near Big Sur, Calif. At least three periods of mudflow activity were delineated for the approximate prehistoric period 1370-1800. Two historic periods of mudflow activity have occurred, 1908-10 and 1972-73. The documentation of mudflows as characteristic surficial processes in the Santa Lucia Range indicates a hazard to development on recent mudflow deposits in this region.
