Alluvial Fans Fan-shaped deposits that form at base of mountains where streams flow across piedmont onto low slopes of playas Pediment -- eroded bedrock surfaces near base of mtns. Bajada -- Area of coalesced alluvial fans Deltas Deposits of sediment formed where rivers flow into sea or lake Fan or &quot;delta&quot; shaped in plan view Subaerial delta plain -- channels bifurcate into straighter, distributary channels Delta front -- subaqueous part of delta where delta slopes seaward Prodelta -- muddy, deeper seafloor seaward of delta front.
