I've done those stalks a bunch.
Many times they bed in a spot thats not conducive for a stalk. It's important to recognize that. They will bed in a depression out in the open sage and you literally need to be 4 feet from them to see their body. Most sloped bedding spots you won't see them when coming in from the top so be prepared to spend hours waiting for them to stand.
in general, the trick is to move fast when you are out of sight and a ways out...but when you get inside about 200y, every step and every noise matters. Most of my stalks were blown due to a bedded deer I didn't see....so the spotting from afar don't just focus on the one animal but scan for others.
Inside about 150y, I take off my pack, put my RF in my pocket, take off my boots and slip on another pair of heavy wool socks or my felt liner sandals, and just carry my bow. I have a thin set of leather gloves I wear too. When crawling just push it in front. When crabbing, I lay it on my lap.
The key is to go Slow, Slow.....way slower than you think.
I'm getting old so I do it less than I used to- I'm just not limber enough anymore...but it was one of my favorite ways to hunt.
