In warm weather with temps only getting down to the upper 50's as a low, will an elk shot in the evening be salvageable (edible) if not found until the next morning (12 hours later)?

I've never left an elk overnight in warm weather to know how this effects the meat. But had the experience of helping my BIL recover an elk over the weekend and was wondering if anyone can pass on their experience with warm weather and next day recoveries with elk and how it effects the meat.
