Mystery Pattern

On Cal Islet, part of Madeira archipelago.  There is an interesting pattern in a rocky shore line. There are some parallel lines, and some art like patterning between the lines.  Also a partial hexagon, three sided next to the patterning.  Could it be something from Atlantis?

The patterns in imagery from provider SRES DRIGOT, a Portuguese provider, shows many introduced imagery errors including the one you have marked. There are more scratch-like patterns south and west of your marked location. There are Newton's rings caused by two pieces of parallel glass being not quite parallel. There are repeated patterns of bits of dust throughout the imagery. The patterns are not a mystery but an expected result of less that perfect image copying. Google might have done better but there are all sorts of restrictions put on imagery it can use over various counties.
