In geology, a palaeochannel, palaeovalley, or palaeoriver (US spellings paleo-) is the remnant of an inactive river or stream channel that has been filled or buried by younger sediment. The sediments that the ancient channel is cut into or buried by can be unconsolidated, semi-consolidated, consolidated or lithified. … See more A palaeochannel is distinct from the overbank deposits of currently-active river channels, including ephemeral water courses that do not regularly flow (such as the Todd River, Central Australia) because the See more There is a large palaeovalley underneath Anangu Pitjantjatjara Yankunytjatjara (APY lands) in the remote north-west of South Australia.
