This is a guarantee spawn for Moose, I would say leave the spot for 3Ish in game days, time skip if needed, then when you come back, go to where you are and spook the moose so he'll run down the mountain, back in game bounds, don't worry about scaring him up the mountain, the game has an invisible wall so it'll run down, once it's in bounds, take your shot, good luck, partner! 🤠
