No, you gave the correct -- and accurate -- explanation for the Bolivian patterns/structures here.
Aside from the fact that both views are of human-modified desert terrain -- viewed from a high altitude -- I see little similarity...
The specific section of Yucca Flats that I "grabbed" shows an uncommonly "orthogonal" layout -- indicative of systematic, planned test sequences designed to measure the effects of a series of development experiments. Other areas of the NTS show much more random layouts - and some areas have very distinctive circular layouts.
The Bolivian irrigation patterns obviously follow natural land (elevation) contours to take advantage of gravity flow for water transport / control purposes. Nary a crater or blast cavity-collapse pit anywhere in sight...
I was just 'funning' you.
