Would you be talking about the Great Salt Lake?
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.
