Elk hunker down when they get pressured by hunters.
They will sometimes go for more than 5-6 days with minimal food and water, before coming out of hiding for some serious grazing and watering.
Find the "deep, dark nasties" that Elk like to hide in.
You won't find them, until you make them come out of hiding.
I used to work with a gentleman that always had good luck around the Brush Creek SWA. But, I don't know if that's close to the area you're hunting in that unit.
