Do I see a circle?

Top half of the image looks to me like it holds a circular feature, possibly a very old crater nearly 'filled'. It appears slightly darker than its surroundings, perhaps because it's depressed and slightly shadowed (?)
Nice boulders in and around it (Pete) and the background is very busy methinks.
Late Edit: Just seen the HiRise image - 'Seasonal Defrosting of Tiny Crater'. Might be a clue there, Hahaha ... * 😃 *
Pete: Interesting boulders and background about half way down the HiRise image.

And to save anyone looking, this is a 2007 image, I've compared with one from 2012 and everything is in the same place and same shape/size. So lumps of rock not ice.

Thanks Wassock, lots of boulders! Seem to be small boulders following plate edges, whilst the larger rocks seem to be more random. Lots of careful marking ahead for me I suspect.Two fairly isolated 'limpet' like boulders at the top of the HiRISE strip.~Pete
