This section of Yellowstone River Trail (NPS) is not maintained by NPS. It really doesn't exist past the Yellowstone River Trail (USFS) that turns north on the west side of Bear Creek. It winds along the slippery river bank that plunges 30 feet down to the Yellowstone, and again it's not maintained. It should not be on the maps because it effectively doesn't exist. A hiker can't hike that trail.
