Park alluvial fan. To the left is the fan-head trench; in the middle
the very coarse deposits of the proximal part of the alluvial fan. These
grade down-fan, to the right, into finer, more sandy sediments. This
fan was created in a single night in 1982 after a dam burst. Link What effect did fan construction have on the pre-existing drainage? |
