I've done it many, many times when I used to guide backpack Dall sheep hunts up north in July, and August. Capes will need to be fleshed, ears turned, and lips, eyes, and noses split to let the salt get in and draw out the moisture. Time consuming, but a must if you want to be sure everything will be preserved for the tannery. The frist day or so, the salt will become almost wet and saturated with fluid. Remove it, but set it aside to dry, and it can be used again. When you remove the first dose of salt, apply another layer for a day or two longer. Depending on what critter you're working with, repeat those steps until the flesh side becomes somewhat stiff and leathery. Roll it up, and put it in a breathable game bag or feed sack. You'll be good to go. Coyote or wolf hides are pretty thin and will get dry quite a bit faster than deer, elk, bear, or moose capes. Bears can be a really big task this time of year because of all the excessive fat.....you will need to remove ALL fat, or the salt will not penetrate to the hide itself and the hair will slip, or start to loosen up and fall out. Be sure to "work" the salt in the lips eyes,a nd ears with your fingers to insure it gets all the way in...consult your taxidermist to walk you through the "turning process". You're basically doing the same exact thing he does in his shop when he preps a cape, or hide for the tannery.
You'll need about three pounds of salt per cape...bring lots to be sure you don't run out! It's cheap!
Good luck on your hunt! Hope you punch all of your tags!
