I've found sign concentrated near the top, around 4500',and near the bottom, around 2-2500'. Found a few creeks still operating and oh boy the area is much cooler near those springs.
Pressure will certainly affect where I go, but I'll go to the coolest and darkest areas.
Definitely hunt down to the bottom in the morning, assuming the elk are in the bottom. Probably start in the middle.
Or hunt up to the top in the afternoon, if I think the elk are moving over the tops near the end of the day.
But this is only my third year so I'm making this up as I go.
