I put this post on trapper talk but maybe should be here please read it if you know of it .

Yep, Cree used that method. Saw it done at the last World XC ski championships in Canada at the Cree encampment

Never heard of it. Spinning carcass, hung on a line, over fire that what you talking about? That is done here and a lot of other places I imagine.

Beaver is often cooked sagabon like geese,but never with the hide on or guts in.they are skinned and gutted and sometimes stuffed and closed up with little sticks.
geese are plucked clean and gutted and sometimes stuffed when cooked sagabon(spun slowly beside a fire vertically from a long string.Drippings are collected in a pan underneath) often many are cooked at the same time for feasts.The old ladies sit around the fire and wind them up every once in a while so they keep spinning.The longer the string the longer they will spin without tending.
meat cooked sagabon is very tender and tasty.
The only animals cooked by first burning off the hair and scraping is porcupine and occasionally groundhogs.

And moose nose

Boco - do you have groundhogs that far north?
If not, I will happily send you some.

Porcupines are cooked with the quills and hide on over a fire by some Athabaskan Indians. My buddy from Gakona mentioned it once .
Said it smelled pretty bad cooking.

Yes porcupine are "swindged" (twist of singed) here too. It is right across the north I imagine. Nothing else though as imagine fur/hides too useful to burn up whenever someone figured that out '000's of years ago. And caribou lower leg bones to crack and get marrow out, and what is inside the hooves too, I believe but never saw that. More old stuff that is dying out.

Boco can speak for himself but I can tell u there is a community north of him on the Hudson's Bay coast named Winisk. Winish means groundhog in the Cree language and in the closely related Innu language that is here. Here they go as far north as about 30 miles north of Nain. Scarce most places except where you can find lots of grass and not saltwater grass. Trees and other vegetation getting scarce north of Nain. Too much cold influence from the Arctic Ocean current coming south. Nain is latitude 56 30. Other places imagine groundhogs well north of that as climate not so harsh as here. English name for them here with some people is raccoons.

Boco lives down South...

Groundhogs are common here around Fairbanks. Noone is sure how they got here, but its pretty certain they didn't walk here... Nobody I am aware of eats them.
