I agree with not getting in a tree stand, at least not on the first day.
I would also recommend to still hunt your way up high to a good vantage point where you can glass the area.
Who knows you may just get lucky while you still hunt you way up the mountain..........
By glassing the area hopefully you will get a few sighting; which will allow you to put together a good plan for the rest of your hunt.
Enjoy your time in the mountains and good luck !!!
