Resumo

Abstract The present Monterey Fan-Valley extends 300 km across the Monterey Deep-Sea Fan with a 400 m relief on the upper fan where large levees border the western bank. Seismic reflection profiling on the upper fan suggests that extensive erosion within Monterey Fan-Valley increased its relief by at least 200 m after it had taken over the lower end of the parallel Ascension Fan-Valley. At present, the latter enters the Monterey Fan-Valley as a hanging valley. A beheaded, leveed valley, the Monterey East Fan-Valley, marks the old course of the Monterey Fan-Valley.
