Colloquial name for the portion of R2F(1/2B1) that is farthest away from the center of the Mandelbrot set; the definition varies but usually it refers to the area west of R2F(1/2B1)S. In extreme cases the term is used to refer only to R2t.
The utter west includes the islands in the R2t series. Each island is 1/16 as large (as measured by e.g. taking the diameter of the .1/2a mu-atom of the island), and each island is located 4 times closer to the tip. See the R2t series article for a list of these islands, coordinates, and formulas.
