That looks kinda like a moose my partner got a doz years ago. It did a DRT flat on its belly between 2 waist high rocks, wedged in tight. He had to do it by boning from the top down. His son was with him but there wasn't room for 2 men to work on it. They had to work in shifts. It took them 5 or 6 hrs to get the meat off.
