Do I have to take the entire carcass of an elk if i want to salvage it?


If I want to salvage an Elk and I'm out in a rural area, Can I quarter up an Elk and drag the carcass 100 feet or so from the road? Or do I have to remove the entire animal?


No.  There is no stipulation that you salvage the entire carcass.  You can salvage any part that you choose and leave the rest.
