Churchill Mountains
From Tardis Wiki, the free Doctor Who reference
The Churchill Mountains were a mountain range on Venus named after Winston Churchill. The Daleks called the region Area XX.
Jeff Stone and his siblings Andy and Mary Stone were on a working holiday in the Churchill Mountains when the Daleks invaded Venus in 2400. (COMIC: Invasion of the Daleks) Some time later, the Daleks constructed a base under the Churchill Mountains, in which they hid their fleet. Jeff and Andy freed the slaves working there, which included Mary. (PROSE: The Secret of the Mountain)
