Elk poop in the woods good luck finding it
Elk scat, rubs, trails, etc are all good, but the only elk sign that gets my attention is seeing them, or hearing them. If that doesn't happen, I could be scaling mountains of elk scat using all 4s looking for them, or trying to hear them. For this reason alone, I will never hunt elk in areas that I cannot see. Giant expanses of dark timber are very hard to hunt if elk are not vocal. Still hunt-able yes, but not enjoyable.
Finally elk sign can look very fresh depending on climate. Don't be the sucker.
I killed my first elk this year in idaho, I found elk by going where I thought no one else would go. I found a nice spot after crossing a stream, trekking through a nasty cow manure mud marsh, and then climbing 2500ft of elevation. I never saw one other hunter
