Illumination is from below. So that is actually a depression, not a raised area. This feature is most likely a dried lakebed.

...with steep sides around the edges. However, that central darker spot in the largest bright area *might* be a slight depression infilled with different RADAR-reflecting properties. Damp muds, for example.

A four-frame VIMS animation showing the evolution of the lake specular point:
Attached Image

Magnified 5x using nearest neighbor interpolation to show the actual specular point pixel size. It's only visible at 5 microns, the green (4.67 microns) and blue (3.26 microns) channels aren't in methane windows, they were chosen merely so they wouldn't be overexposed in the longer exposure cubes.
