In this VIS image, taken by the NASA - Mars Odyssey Orbiter on February, 18th, 2014, and during its 54.044th orbit around the Red Planet, we can see a so-called "Streamlined Island" (---> such as a Vertical Relief - that once, probably, was an actual Island - found in a - now - Dry Riverbed and characterized by the presence, all around it, of solidified Flow-Features).
This Streamlined Island is located in a relatively broad Unnamed Channel found in the Chryse Planitia Region of Mars. The Channel hosting the Streamlined Island, on its side, is part of the Outflow Region of Lobo Vallis, which is a Northern Branch of the Complex Kasei Valles Outflow Channels' System. As you cans see, only a few - and, mostly, really small - Impact Craters can be seen on the Riverbed as well as on the Relief making the Streamlined Island, and this circumstance suggests - like we already underlined several other times, even though for other, and yet similar, contexts - that this specific Channel should/might have lost its Waters in recent times (of course, always relatively speaking). Last, but not least, the slight decoloration that you can see to the South of the Streamlined Island (i.e.: some sort of a "whitish and elongated patch of land") could reasonably be a Windstreak.

This image (which is an Original Mars Odyssey Orbiter b/w and Map-Projected frame published on the NASA - Planetary Photojournal with the ID n. PIA 18199) has been additionally processed, magnified to aid the visibility of the details, contrast enhanced, Gamma corrected and then colorized in Absolute Natural Colors (such as the colors that a human eye would actually perceive if someone were onboard the NASA - Mars Odyssey Orbiter and then looked down, towards the Surface of Mars), by using an original technique created - and, in time, dramatically improved - by the Lunar Explorer Italia Team.
