Joey;
Good evening to you sir, I trust when you read this it finds you well.
In my view and experience hunting in the BC mountains sometimes north of Idaho, but mostly north of Washington, I'd say you've been given some very good pointers and none of the responses from Fireball, Lonny or Westman had anything I'd add. Good stuff gentlemen.
Not being from the coast, I can't comment on getting used to the altitude, but that makes sense too.
If it was me telling someone how to chase black bears here, I'd suggest perhaps for their first mountain hunting experience, especially with a youngster, to consider shorter day hikes and hunts, returning to the rig and camping out of that.
As Lonny said, we can look at a lot of real estate here without seeing much of anything moving in spring. We'll typically drive to a spot where we can glass the south facing slopes of a drainage, glass for awhile and then try to get to another drainage or at least a different section of one.
Bears here are pretty much head down and eating when they get up, so again looking for clover patches is a good start.
Watch for wood ticks in spring, they were worse than usual this spring here.
If you spot a bear, look at the ears. If they look all leggy with ears a donkey would be happy with, it's a young one.
This one is likely at least a year and probably two years older than the top one. Notice how the ears look shorter and the face more filled out.
A bit of a lousy photo, but we can see this guy has clearance issues - not leggy - and the ears barely stick out. He's still not huge, but he's a mature Okanagan boar.
This I believe is the same bear 4 years later and he's even more of a blocky shape in this one.
In summary, for sure a GPS - maybe maps too - there's a lot of ground to get turned around in when we're up in the mountains. Try to pay attention to which way the drainages and feeder creeks run too.
Good gear is tough to know without testing, so get what you believe to be good gear and test it with shorter runs so both you and the gear get used to the steep places together perhaps?
Hopefully that all made some sense and was useful.
Good hunting and all the best.
