It is good to see and know that not quite all wild terrain is subject to ADFG Intensive Management.  I salute the sanctuary and the effort behind it and Clem Tillion's sponsorship of enabling legislation. It has to have been an enlightened legislature, far apart from the present  legislative - endorsed wildlife holocaust of predator control savagery meted out by our rogue Game Board, executed by ADFG and privateer authorized pilots.  To wit: 2012-14, 421 black bears killed and 34 brown bears, as Intensive Management, and in a state professes to honor the bear on its license plate.  Numbers from ADFG records.
McNiel River Sanctuary is a place where relative few of Alaska's bears are safe to live their lives while many of the rest of us anguish over the commonplace  shameful slaughter elsewhere that is a matter of public policy
