Wildlife photographer Donald M. Jones was shooting on the East Fork in Denali National Park, Alaska in September of 2004 when he caught the story shown in this slideshow on film. Some wolves had killed a bull caribou in the night, but when the sun came up a sow grizzly with two cubs of the year spotted them and chased them off the kill.
The wolves kept trying to retrieve their caribou, and the sow kept chasing them away. This repeated for a day and a half, after which the sow and her cubs decided they'd had enough. After they left the wolves returned (an alpha male and female), and had a half an hour with the kill before a large boar griz came along.
This big male gathered all the body parts (see elk leg photo), put them in one pile, then laid on top of it and fell asleep (last photo).
