I have to say that one of my favorite places to hunt I am never more than 100 yds from fresh grizzly sign. Lots of elk, plenty of grizzlies. I also definitely never miss an evening hunt it’s the magic hour! I do ditch the rifle for my shortbarreled 12 ga 870 when retrieving quarters that were left overnight!I've spent 45 years bow hunting/fishing in griz country in MT, WY, ID, AK and Russia. A few close calls to learn from. I have been seriously charged and lost a nice moose to a grizz.
Clean camp......no snacks in tent, no food cooked in camp, no food stored in camp. Hang your food 10 feet up away from camp. Camp in open areas.
Bear spray....fresh and readily available...not tucked in your pack or under clothes. A spray isn't infallible but better odds than instantly killing a fast charging bear with a pistol IMO.
Think twice about hunting evenings. Don't leave a killed animal overnight. Good chance a griz will be on it in the morning and you have a good chance of killing a griz or getting injured/killed if you try to retrieve it in the morning.
Hang meat at least 10 feet up and in a spot you can glass before approaching it.
If you see fresh griz activity just leave.
Make some noise if you cant see well ahead or at night.
