Here is a Dakota firepit. You dig it in the dirt when you dont have another way to cook. Its safe with the fire in the ground. It burns hot and efficiently with sticks like a rocket stove. Here is a diagram of how to dig one. Then is a shot of our groups pot of 21 bean soup. You can see it has to be hot to boil a pot of water that big. This is also terrific for boiling water to sanitize it!
