That section of the map overlays very closely with the Navajo reservation. AFAIK that area has high levels of poverty and a lot of homes do not have electricity at all. See this article that came up on search: https://amizade.org/keeping-warm-in-the-navajo-nation/
Ok that makes a lot of sense. Though, there’s two of these areas in the desert. One maps pretty strongly to the Navajo Nation, the other seems to be in the middle of Nevada.
Ok that’s weird to me. I’m from the Mississippi basin/great lakes so I always imagined the deserts as barren except for cacti. Though I suppose y’all may not expect our mountains to be so thoroughly forested. This continent sure is weird at times
