Cooking Fires
FIREWOODS - There are many things which make some woods burn hotter
than others - rate of growth, resin content, age of tree, part of tree,
structure of the wood itself. As a general rule, fire making woods that
are good for making friction fires make bad firewoods, since they are
low density and resinless. The best woods include oak, hickory,
madrone, manzanita, mesquite, and other dense hardwoods. The worst
woods include pine sapwood and many other softwoods and willow,
although these make good kindling. Wet wood burns cooler than dry wood,
but burns relatively longer. Heart wood burns hotter than sapwood in
general. Rotten wood is good for producing smoke, but not heat or
light. Charcoal burns hotter than the wood it was made from as the
volatile gases which produce flames burn at a relatively low
temperature. So your coals are the hottest part of the fire, not the
flames. Light comes from the burning gases. The firewood you can
actually get always burns better than the firewood you wish you had,
but you'll need more of the poor stuff. Think of wood as calories.
Better wood has more calories per piece, so can do more work.
The easiest, but slowest way to get a bed of coals is to build a huge
log fire and wait a few hours. This takes the least effort and the most
wood. To get quick efficient coals, burn small pieces of wood. In the
Scouts, the rule was to find wood (or split it into pieces) the
diameter of your thumb. These were neatly stacked next to the fire and
added as needed to maintain a constant temperature. When cooking
directly on the coals, the new wood is added at one end of the fire and
the coals are pushed down into the cooking area. If you are using wood
that doesn't make coals, you need to add pieces very often to maintain
any he

Fire pit construction varies according to weather conditions, wind
direction, what and how much you are cooking and the type of fire wood
that is available. Once your fire is started the two important things
to manage are fuel, mentioned above, and air flow. If you are building
a fire in a windy place such as the grassy plains of the Dakotas, you
need to dig out a deep fire well.
The extreme version of this requires two holes dug about a foot deep
and a foot apart. They are connected at the bottom by a tunnel. A pot
or grill (or big piece of meat) can be placed over one hole, while the
other provides access for fuel and air. The Dakota fire is also very
efficient, requiring less fuel, as almost all the heat is put to work.
Moderately windy conditions can be handled with a wind screen of rocks
or logs.

My standard cooking fire is dug down about four to ten inches,
depending on soil type and wind. (Save the soil and sod if you can to
put back when you're done.) If the wind is not too strong, line up the
pit so the breeze flows parallel to it. Make sure the wind isn't
blowing the smoke to where you want to sit while you cook. The pit is
then lined with the flattest and driest stones I can find, including
the bottom. Stones that contain moisture tend to explode as the water
becomes steam. The stones come up another four to six inches above
ground level.
If I am going to do a pit roast, another, deeper pit is dug a foot or
so past one end of the main fire, and the hump of dirt between the two
is not rock covered. Pit ovens should be dug deep and wide enough to
accommodate a stone lining and a green vegetation lining as well as the
food. The area between can be used to generate coals to replenish the
cooking area, heat rocks for stone boiling or covering the baking pit.
The length of the fire varies according to the number of people
cooking, the width is from one and a half to two and a half feet. One
or two people can easily cook on an 18" round fire.
