Lots of great info provided.
Before leaving the meat, put up some tree branches (think tripod or teepee) that would easily get knocked down if a big predator came in to claim the kill. Nice visual indicator.
Do what you can and just go from there. Tons of folks live, hunt, camp, hike, recreate, etc in grizzly country and the vast majority are not hyper vigilant. From a pure numbers perspective, the odds of a bluff charge/pepper spray/warning shot/getting mauled/getting killed/etc is pretty damn low.
