I have always felt it would be a good idea to take the CO to the carcass, have him point out the edible portions, then give it to him. I'll pack it out but he can eat it.
In all seriousness, I think a mountain grizzly would be pretty good eating. However, trichinosis is always a concern, especially in a mountain bear, so treat it accordingly. I know a lot of people who prefer grizzly to black bear for which the same cautions apply. Likewise, if you eat marmot, cook it well and avoid eating the entrails (most will have no problem following these instructions). GD
