If you have access to a chainsaw some dry softwood and a Swede here's a great way to make a self-contained camp fire with integrated pot supports!
Step 1: Cut 3 Slots In The Log.
Unfortunately I am not dexterous enough to use a chainsaw and take pictures simultaneously. Sorry.
Use the saw to cut at least 3/4 of the way down the length of the log.
Step 2: Build A Bundle Of Kindling In The Middle Of The Log
As this kindling burns the thin sections of the log near the top will start burning and air will be sucked through the cracks lower down
Step 3: Light Your Fire!
You'll notice that after a couple of minutes your fire will descend down into the log completely protecting it from the wind.
Step 4: The Outer Layer Of The Log Should Remain
On these outer sections of the log you can place your pan!
Step 5: Modified Example
Here's another option- I you have some lumber lying around you can tie it together with spacers (nails) between the pieces to allow airflow in. It's the same concept. But with found scrap lumber!!!
