Yes, it's not known for its high ISO night shooting, but I had to give it a try. I thought that the sky was usable, and with enough light on the foreground, a foreground subject might be brought into the composition as well. Obviously there's little shadow recovery possible. This was adjusted with the exposure and shadows a bit, and there's not much detail to be found. Lighting is therefore the key.

(Given the typical summer national park crowds, plus a healthy additional load of eclipse photographers, this wasn't really a practical time or setting to test that.)
