The editing I've done here is quite minimal. I bumped the contrast and sharpening a little bit to make the edges between the layers more well defined. A little increase in clarity can also help achieve this.

I don't think this is relevant to your photo, but for the sake of full disclosure I did edit the colour of this photo a little bit In the raw I found that each successive layer became slightly more orange than the last (likely because the haze was wildfire smoke) so I added a graduated filter with a slight blue tint to counteract the orange and give the layers a more uniform look.
