I have been hunting in wolf and grizzly areas for the last several seasons and usually build a fire at the kill first as the smoke will help keeps the bad boys away, then field dress and quarter and hang, then come back with horses the next day, a few occassion I left the quarters not very high but lucked out and nobody got to it. I think the smell of a small campfire helps.
I usually gut an elk enough to get to the rib-eyes, but leave the bladder and lower intestine etc all attached as to not risk anything... like others have said there is little need to gut if you in the backcountry and are skinning, quartering and boning out the backstraps.
