Channel in Lucus Planum (3-D)

May 29, 2012
Lucus Planum is a part of the enigmatic Medusa Fossae Formation, a broad, soft, and easily eroded deposit. Here this deposit is thin and considerably rougher than elsewhere, implying that it is heavily eroded. Here a channel can be seen cutting into this deposit.
