Yes, there are bear up there. Plenty.
I've seen 'em as close as 100yds from the Baker Lake CampGround (the one near Upper Baker Damn/Depression Lake).
I've also almost roadkilled two of 'em up there in the past decade.
One thing you will run into in many areas up there are "granolas" (a term for tree-hugging yups). They have a lot of high lakes and scenic trails around Baker Lake...including amenities for horses.
I'd prefer not to post a bunch of areas online, but I'll PM you some general info. Check your inbox.
