Nope, go to the map in the link and zoom way in in sat mode. Keep the epicenter marker in the center. Just below the official epicenter, there is a large array of light splotches in a rectangle. There are a few 4x4 roads going in to the area.
The lake and salt flats and so forth are far away at that scale.
Also, look at the map I linked, it’s alredy zoomed in. Somebody did something there in a grid.
My presumption is they’re either mining of some sort, or an OHV area, and maybe also patchwork differences in satellite pictures. Sometimes the called-for image is a spliced-together collage of pics taken at different times and days.
My guess would be oil/gas exploration.
Probably a layout grid of drill pads for some type of exploration (anything from mineral to geothermal evaluation).
