> "Rubble Landscape": A square outer rim of the caliche layer of stone is dynamited and bulldozed into a crude square pile over the entire Keep. This makes a rubble-stone landscape at a level above the surrounding desert, an anomaly both topographic and in roughness of material. The outer rim from which rubble was pushed inward fills with sand, becoming a soft moat, probably with an anomalous pattern of vegetation. This all makes for an enormous landscape of large-stone rubble, one that is very inhospitable, being hard to walk on and difficult to bring machinery onto. It is a place that feels destroyed, rather than one that has been made.

"Landscape of large-stone rubble" describes, among other things, New England, where all of those stone boulders were carefully (or more often carelessly) stacked into stone walls to more-or-less clear the fields for planting or pasturage.
