Scepter Valley    

Robert P. Munafo, 2023 Apr 18.



Also known as Seahorse Valley West, this is a colloquial name for the cusps between R2.1/2a and R2.1/2.1/2a, particularly the upper one, R2.1/2.C(1/2)-. See also Double Scepter valley.

When distinguishing features on opposing sides of the valley, the side closer to R2.1/2a retains the name "scepter valley" while the side closer to R2.1/2.1/2a is called dragon valley. The embedded Julia sets found in an island's "scepter valley" are sometimes called scepter medallions.

This picture shows the reason for the name: a seahorse with "scepters".
