Adding intense distance fog, can't find a solution.

See the below link as a reference. Basically, I’m trying to do a similar thing with the mountains as done below. You can tell from the perspective that there’s actually not a lot of distance between the mountains and the foreground. However a lot of blueish fog is added to the mountains, making the ones in the rear seem far away.

I’m trying to get the mountains in my map to look just as far away, but using the elevation exponential fog, I can’t get nearly the right amount of fog to achieve this. Additionally, I’d need to set it just for the rear of my map.

Any solutions or ideas?

Thanks.

*I suppose I could simply color the mountains in the rear with a desaturated blueish like color. Just wondering if there’s a simpler way to achieve this.
