I also use it to dig a small fire trench.
Remove 2" top soil with grass etc. Place it out-of-the-way. Dig a small trench,slightly smaller than your pot diameter. The trench needs to be in-line with prevailing breeze. Light fire in trench. (Remember, small sticks burn quick and hot, thick sticks burn slow and bake) When you have finished cooking, extinguish fire, "no steam rising from wet ashes". Bury ashes with soil dug from trench. Then cover with topsoil disturbed earlier.
