The teepee fire is probably the most recognized campfire. It is somewhat difficult to lay however, as getting the logs to balance against one another can be tricky. Sometimes the log pile will topple and upset the kindling and tinder beneath, and you'll have to start again from scratch. If necessary, you can lash them together at the top with twine (but don't use a synthetic rope such as nylon or polypropylene). Once laid, the teepee fire is very easy to light, as convection will take the flames right to the fuel.
Adding fuel to a teepee fire can also be challenging as the balance problem is still there, but it is now complicated by the presence of heat. For this reason, teepee fires often devolve into a chaotic heap.
