My wife and I had a great encounter with 06/832 on a roadside kill in the Lamar valley in summer 2011. 06 was well known for killing elk by herself. Late in the day in YNP, we saw a small group of people watching a coyote feed on a just killed elk about 80-100 yards off the road next to the river. 06 had just left to bring some meat to her cubs and we had a couple glimpses as she trotted up the valley away from the kill.
We woke up at 4 am the next morning, and we were parked next to that elk kill before light got into the sky. 2nd car there, best seats in the house, front and center. When it was light enough to see, we and a few other people who had shown up, see a good sized grizzly sow asleep literally on top of the torn apart dead elk, like sleeping inside the rib cage on a pile of meat. It was foggy, so visibility wasn't always great, but the fog burnt off in about an hour. 06 showed up to get some meat around 730, her mate (955?? Dark blackish wolf) about an hour later. For the first hour, they just sat in the bushes and waited for the grizzly to leave while occasionally cruising around the river bar where the kill was. Then they got sick of waiting and took turns harassing the grizzly and getting it to chase them. Every time the grizzly left the kill, the other wolf would dart in to feed it tear apart the elk. They would take turns doing this so each could eat, would sit on opposite sides of the bear. Sometimes the grizzly would go back to eat more elk and go back to sleep on the elk and the wolves would sit 10-20' away from it with nothing happening at all. The grizzly had eaten so much elk her belly was like a beach ball, she had trouble running with it. Eventually the grizzly left and the wolves took more elk back to the den, like dragging off a big heavy leg, and it was over.
All told, we watched them do this for for 3 hours or so that morning. Saw at least 50 lbs of elk get eaten. Probably 250 people there watching by late morning, they literally had the road closed and police traffic control there by about 9 am. Neither the wolves or bear seemed to care about the massive crowd that was eventually there.
NYT wrote an obit the next year when she left the park and was killed:

It was worthy of Marty Stouffer and his camera. Was lucky to see it.
