HUNTING -- I've killed an elk near a road where it could be loaded in a pickup exactly zero times in my hunting career.
Every one had to be quartered or the meat removed from the bone in the field to be hauled by a pack animal or, in most cases, by me and a buddy on our backs or on a cart.
In the following two videos, pro hunters demostrate the "gutless method" of deboning meat and getting it ready quickly to pack out.
The first, published in 2015, is by Elk101.com's Corey Jacobsen provides a step by step tutorial on the Gutless Method for processing an elk in the field. Corey shows the entire process (including removing the tenderloins) to get the elk quartered and ready for packing. 12 minutes.
Next is a longer demonstration published in 2016 by Randy Newberg, who shows slightly different methods of taking care of an elk in the field without having to remove the entrails. 27 minutes.
