With this observation, we see some candidate lake deposits possibly fed by alluvial fans in the distant past. At high resolution, we can check for layers and layer tilts to test a lacustrine hypothesis. Tilts more than 2 degrees suggest the origin is *not* lacustrine, but rather from a distal alluvial source.
