This might [also] be a matter of perspective.
I'd suggest rotating your isosurface or repositioning the camera to see if it
goes away, and what you _think_ you should see is actually there, or an illusion
or unexpected result of the texture and/or lighting.
(align your spiral so that it is symmetric around the y-axis)
I might also move the light source, and perhaps add one or two more.
