It's a circular formation that looks, to me, like an elevated plateau. Since about 1/2 of the formation is in the river channel it seemed obvious that it is resisting erosion and is probably an old island.

The rocky island is very unique in the Lena Delta area because the land is mostly made up of ice-rich frozen fluvial peat and sand. This is what makes Sardakh more resistent to the natural erosion that casues the other areas of the delta to so readily shift. If anyone has been up in that area, I would love to see some photos.
