There are some times where you just gotta give it a go. That stand sounds like that situation, and in the rut when animals are moving, and you have the chance a mature buck is concentrating more on ground scent might be the time. His guard is down a bit, he's moving way faster than normal etc. Especially on a clear cold night, where you know you may have a massive warming thermal in the morning saving your bacon.
I had one tree where I killed a ton of good bucks from in the rut, but I never knew where they would come from, so I just sat it regardless of wind, but I'd wait until the rut to do it. The tree was just in the right spot. Good luck with the hunt!
Are there any spots up on the top edge of the flats above, or near the pinch points where you can see below, and could hang a stand and possibly brush it in a bit (if it’s naked) or put in a ground blind, and try calling, rattling, etc., to pull a cruising buck to you?
Now... If you’ve ever studied fluid dynamics, this might go without saying, but if there is an open area exposed to the prevailing winds, the air currents where you are will flow on that direction. One sure-fire spot I have hunted many times just proves it; the scent-flow there is nearly 90 degrees off of the prevailing winds. So much so that I call that spot the fish-barrel; as long as I’m 10 feet up, it’s practically fool-proof. Another spot at the leeward end of the open area, the air moves 180 degrees opposite the prevailing winds. As long as you are Just Deep Emough into to woods. A few paces further and you’re toast.
Just find the tightest pinch-point that’s closest to an open area or otherwise presents minimal resistance to air flow in that direction - a power line cut is good, or just thinner tree cover.
Air currents at ground level will be more influenced by thermals; find a minor trail down-thermal of the scrapes that the bucks will be scent-checking and set up fairly high at a comfortable distance down-wind (based on prevailing winds sucking air out of the woods toward the open areas).
That’s what has worked for me, anyway...
Good luck with it!
Up? Usually, I see the cooler air flowing downstream.... have used that repeatedly when hunting Elk up high.
One afternoon I was easing along and saw A Leg swing off the trail up ahead. Coming my way60-70 yards up. So I hustled back to the last gully I’d crossed, climbed up about 50 yards then headed back in my original direction and came down on top of the herd from above while they were still looking toward where I had been seen and scented just earlier.... The prevailing winds and thermals had been pushing my scent up-slope, but in that cold gully, the local thermals were 100% down-hill.
It’s like using an elevator to leap-frog someone who’s looking for you to take the stairs.
