If you have a sawmill near you, get some sawdust, set racoon on the ground and then cover well. No odor and it will be nothing but bones in a couple of months. I did it with a goat once and there was nothing but bones left behind. No fur even. The ground was raised up where the goat’s organs would be. Microorganisms are amazing.
You could probably put a couple of inches of sawdust down first as a bed/base, then add coon, then cover. Wouldn’t hurt to wet the base layer. Microbial life needs water.
I gave our dog a proper burial but I wasn’t about to dig in this heavy, rocky soil for a goat. Sawdust worked great and since it had no odor, nothing bothered it. If you have an outdoor cat, they may use it as a litter box. You could lay some fence or poultry netting or even a tarp over it and weigh the edges down. I did the goat during the wet season. Since it’s summer, it probably wouldn’t hurt to wet all the sawdust down and put a tarp over it. Or at least all the sawdust in contact with the coon. Need a good home for the microbes. It is a compost pile after all.
